I had like 3 friends ask me how to build a PC in the past week so I made this to help them.

(Reddit Edit: Help my improve the document with productive constructive comments on what I got wrong or messed up! Im only human lol
Also a lot of this is supposed to be kinda humorous. I didn't think I had to say that but, hey, its the internet.
I appreciate the positive and productive comments! )
Beginners basic guide to building your own PC as of early 2018
(EDIT: Sorry for being a MSI/Corsair Fanboy)
Heres a collection of thoughts to consider when building your own personal PC
As always Id personally use PCPartPicker.com to configure your parts and for further thoughts on compatibility.
First off building a computer is 100% based around what you plan to use the computer for.
Here are a few uses and generic ideas of what to go for. Audio Editing: Lots of small tasks that need to be completed quickly without lag. - Fast Processor( >4GHZ) - Fast RAM (MHZ) -At least 16 gigs! - Fast Storage, SSD manditorily - M.2 or PCI for best performance. - Shitty Graphics card, graphics card there only to keep the cpu from doing other tasks when working. - Can be a few generations or years old. - Many screens for lots of plug in windows to be open Video Editing: Lots of large to render and files to read. - Multi core processor the more the merrier - SSD for fast read/write of large video files. - Insane graphics card, AMD graphics cards are debatibly better but the nvidia Quadro series are specific for video rendering. Gaming: No more than 4 cores intense graphics card - 92% of games are not coded for more than 4 cores so why spend the extra money for it. - SSD for quick load screens - Nvidia cards, 10 series, the higher the number the better. Titan cards for MAXIMUM OVERDRIVE! Coding: quick processor for lots of small tasks. Ergonomic peripherials? - Dear god please dont use a mechanical keyboard so that your coworkers dont kill you. Home office: Everything can be a few gens behind so you can get the best power per dollar spent. - Sorry that Gateway doesnt exist anymore. I guess try Dell... 
Parts (Expensive Legos)
CPU (tells things to go places and outputs data) Basically three main routes to go for: Intel, AMD, or ASIC. Intel - Gaming, Data center, Hackintosh Pros: Cooler, Faster speed (GHZ), short small tasks faster Cons: $$$$, less cores AMD - Gaming, Personal Computing, Large task processing Pros: Lots of cores, better price per performance, faster processing of large tasks Cons: Hot chips, large chips?, compatibility issues with MacOS. ASIC - "Application-specific integrated circuit" Pros: Does the task that they are made to do insanely efficently, great for mining. Cons: Literally does nothing else. Holy hell these are expensive, very hot (fans will get loud) CPU Cooler (Im a big fan) Most come with an in box cooler that are ok but please buy aftermarket. In Box - the free shitty cooler that comes with the processor. Pros: Free. Cons: Ugly, makes chip run hot, hard to clean Air cooler - oldest type of cooler but new designs are highly efficent. Pros: Only cooler that has the possibility of being 100% quiet, most likely cheaper Cons: large, if cooler isnt large enough for the chips thermal output the fans will be loud. Liquid - Custom pipes are beautiful, AIO is easy to install and offers similare performance. Pros: Looks cool, great temperatures, "quiet" Cons: Water pump has possibility of being loud, possible spills Phase Change - uses the technology of refridgerators to cool the chip Pros: Can overclock until the chip breaks. (whats colder than cold? ICE COLD!) Cons: Loud (compressor noise), Large pipes, just why.... Motherboard (the convienacnce store of computer parts) Really just about what type of I/O you want. - MAKE SURE FORM FACTOR FITS YOUR CASE! (or vice versa) - Look for PCI lanes for expansion. - How many graphic cards do you have? - PCI based interfaces? - PCI SSD? - PCI DAC? - PCI WIFI? - USbs? Network? Audio? - How many lanes of RAM? - DOES IT FIT YOUR PROCESSOR!?! (really tho) - M.2? - How many sata interaces? Good Brands: MSI, ASUS, Gigabyte Bad Brands: AS(s)Rock, Dell Memory (Dory) - The more the merrier - No less than 8gb for a functional windows machine (16 gb to never have a problem) - Use all the lanes your computer has to offer! the more lanes to access the faster the data can travel! -Imagine drinking a milkshake. If the straw is wider you can drink more of the milkshake than a skinny straw. - Faster MHZ for faster data access but give minimal performance differances - Please get ram with heat spreadders unles youre building a server with high airflow. - Make sure the type (DDR3 or DDR4) of RAM matches what your processomotherboard call for. Good Brands: Corsair, G.Skill, Ballistix Storage (Grandpa that remembers everythign about how things used to be but takes forever to learn a new tasK) Speed or massive storage? slower is cheaper. Golden ratio of speed/storage/price is 250-500 gb SSD and a 1+ tb disk drive. *Max speeds listed are for a single drive not RAID* Hard Disk Drives (HDD) - Cheapest and slowest - read/write speeds of < 0.5gb/s - 7200+ RPM or GTFO - Higher Speed drives can access data faster. - Do not move while powered up. physical parts will break. - Larger Cahche = faster Read/Write Speeds Pros: Cheap, Holds massive amounts of data Cons: Slower than molasses in a frezer Reputible Brands: Seagate, WD Solid State Drives (SSD) - necessity for quick boots and fast load screens (can only be re-written to so many times) - SATA based (2.5 inch)- Read/Write speeds capped @ 6 gb/s Pros: Most economical, form factor fits with old computers, Cons: "Slow" compared to other ssd's (but stil 12 times faster than a HDD) - M.2 based - Read/Write speeds capped @ 10 gb/s Pros: Size of a sick of gum! High End but not too expensive to be out of reach. Cons: Expensive for any size over 500 gb - PCI based - Read/Write speeds capped @ 20 gb/s for PCI3, x4 Pros: HOLY BANDWIDTH BATMAN! Faster than that little creepy ghost thats always in the corner of you eye Cons: You might have to take out a loan to buy one. *takes up a x4 PCI Lane* Reputible Brands: Samsung! Corsair, Plextor, Intel, Kingston, Crucial Video Card (that one kid that has thick glasses and is really good at math) - A regular old PCI card that handles all of the video rendering and output for your computer. - ASIC PCI cards. - The PCBs and chips are patented by two main companies but the differances come from line up and varying manufacturer cooling devices. - The more memory the better -NVIDIA (Team Green) Great for gaming, has specific card series for intensive rendering. Lazy driver updates. - Gaming - 900 series - Cheap - Low performance - Can play any video game made befrore 2010 on max settings - 1000 (ten) series - Expensive (thanks bitcoin miners...) - Great for VR! - Video Rendering -Quadro Series - Gaming and Rendering - Titan X - Maxwell based chip same as 900 series cards - Titan XP - Pascal based chip same as 10 series cards -AMD (Team Red) Underdog does the same thing but slighly worse and cheaper. (except video rendering) - Gaming - RX 400 series - Cheap - Hot - RX 500 series - Cheap - Ok at VR and deacent gaming frame rates. - Not bad but not particularly great either. - Video Rendering - Fire Pro series - Gaming and Rendering - Vega series -Good luck finding one to buy lmao Case (Fancy clothing for your parts!) - Similar to human clothing you want it to do a few main things really well with compromises for each extreme. - Durability - Steel - Incredibly durable - Creates Farady cage for components - Heavy af - Magnets, just magnets.... - Rust over time - Aluminium - Light - East to bend for modding or "physical maintenance" - Less likely to rust - Huzzah for Farady cages! - Plastic - Just dont - no electrical Ground - no faraday cage - Light AF! - Breath (Airflow) - positive internal airflow! - larger fans push the same amount of air with less speed/noise - Looks - Window? - RGB - Cool Paint? - Fit all your parts - graphics card length/ clearacne - support for liquid cooling raiators? - How many spots for HDD/SSDs - Motherboard format - Cable management! Power Supply (FIGHT MILK) - Rule of thumb: BUy Powersupply that outputs 1.5 times the wattage that you need. - You can walk further than you can you can run. - The PSU can casually output 50-75% power for much longer than at 90-100% (without failure) - If you never demand enough wattage for it to get hot the fan doesnt have to turn on therefore making it quieter. - Modular means you can remove/replace the cables from the PSU. Reputible Brands: Corsair, EVGA Optical Drive (motorized cup holder) - You can download most things today so I'd suggest against it unless you really NEED to watch/write DVD's/CD's Operating System (software that makes everything work) Windows (Always Updates) - Compatible with just about everything - Easy to learn to code on! - POS inital browser - Likely to get virus's Linux (Penguins are cute) - Unique - takes less resources to run - Barebones - Incredibly personalizable! - Compatibility issues with just about everything MacOS (Linux but more annoying) - It is legal! - Great for art and your grandma that doenst know how to use computers! - User friendly - Compatibility issues with various hardware - Confusing/Limiting coding structure Peripherials (cables everywhere!) - Keyboard (higer Polling rate is better) - Mechanical (key is pressed at an exact stroke length every time - Mouse (Higher Polling rate is better) - more buttons = better? - DPI (Dots Per Inch) - In theory, if a mouse has 1600 DPI, then, if you move your mouse one inch (2.54 cm), the mouse cursor will move 1600 pixels - Higher DPI the faster your cursor is able to be moved. - Monitor - In theory the human eye cant see faster than 60 frames per second. - Keep in mind Pixel ratio! - 4k screen that is 22inches will have more pixels in a square inch than a 4k screen that is 28 inches. - Interface? - DVI (Analog) - thumbscrews..... - can do two monitors with one port! - support for 4k - VGA (Analog) - thumbscrews... - max resolution is 1440p - Display Port (digital) - nice button clip - supports 4k - HDMI (Digital) - 1.2 or higer supports 4k - DAC/Speakers/Headphones - Dont even get me started - Microphone - Dont get me started PT.2 Other (other) - UPS (uninterruptible power supply) Just a battery that allows your computer to have some time if the power ever goes out so that you have time to save your work. - Cable Organization materials! - Zipties - velcro - LED LIGHTING! - Manditory - Extra/Better fans - More pressure, less woosh - IFIXIT Pro Tech Toolkit - becasue who buys just one torx wrench. - Cute kitten mousepad - Yes, it has to be a cat. Dont argue 
This is a very general entry into building computers and what you should buy/look for. If you have any questions/comments send me an e-mail!

To all new miners, please read before posting

Hello everyone!
This subreddit has gotten a lot of new miners since Bitcoin has skyrocketed and NiceHash has been hacked, and since very many posts regard the same type of subjects, I've compiled a bit of valuable information that beginners can use.
Before we start I want to say that there's a lot of information on this topic, so looking in the sidebar as well as doing a simple Google search can answer many questions. I'm not a moderator on this subreddit (PM me 'nudge nudge') nor do I claim to be a professional on this subject, I just want to supply information for beginners and make the subreddit cleaner. Let's get going then!
Do note that not all mining is profitable, old GPU's, CPU's and even some ASIC miners are not profitable at all, and will result in a higher electricity bill that outweigh your earnings. That being said, a good rule of thumb is the newer the tech, the more profits you'll recieve. A good way to know how profitable your GPU is, is to enter the hardware you have here and look at the most profitable coins for you to mine.
Having entered your hardware at whattomine.com it will show you the most profitable coins to mine. Good, more popular recommendations are: Ethereum (ETH), Monero (XMR) and ZCash (ZEC) and some upcoming coins are Monacoin (MONA), Vertcoin (VTC) and Zencash (ZEN). Not a complete list but a good place to start.
The most important components are GPU's, PSU's and Motherboards. Focusing your budget on those is a smart move. Look up your graphics card's TDP, multiply it with the amount of cards you want to use and add ~300. That gives you the amount of Watts you need to power everything, and accounting for the rest of the system as well as some margin. Sometimes you're gonna need more than 1 PSU, and getting efficient PSU's is really important. The bigger the rig you want, the more PCI-E x1 and x16 slots in your motherboard. CPU, RAM and storage is not valueable in a rig, although having a full hard drive and a slow CPU will slow other usage down i.e. during setup/maintenance.
You're going to need a wallet to have your money in. Search for the coin you want to mine and wallet, you'll be guaranteed to find something. Different currencies have different algorithms and different mining software support different algorithms. Search for the algorithm of the coin you want to mine and then find a suitable miner. Some names to remember are Claymore and CCminer as they support a plethora of coins. Other than that you'll need overcloking software (e.g. MSI Afterburner), Hardware Monitoring software and if you want to manage your rig remotely (which you will want to do) then TeamViewer is helpful.
Again, Google is your friend. Find a computer building guide, and once the rig is built there's a tonne of mining set up guides for every concievable coin, wallet and pool.
Lastly, I want to make two things very clear before you start. If you're not a tech-savvy guy then it's not worth doing. It's gonna be a lot of bugs and problems and if you haven't built a PC before it's going to be almost impossible to make everything work. And NEVER SPEND MORE THAN YOU CAN LOSE. To start mining with a decent rig, you're gonna need at least 1500$ for a new decent rig that doesn't have a 10 year ROI. If spending that money will hurt your economy, don't do it. A good tip is to start with the PC you already have to get a grip of all the software setup and start gaining mining experience.
Good luck mining!
TL;DR: No, you cannot mine with your printer.

My Experience: From FX-8350 to R7-1700

Upgrading from an FX-8350 to a R7-1700.
Just a bit about me – I have been building computers since the mid 80’s. I missed the 8-inch floppy disk era, but came on board when dual 5.25” was considered mainstream and a 10-megabyte full-height HDD was the mark of a power user. The first computer I built for my own enjoyment was an AMD X5-133 (a factory overclocked 486 faster than the Pentium-75), and I’ve used a wide variety of systems since then, including a Pentium Pro-200 which served me well in college and a K6-2 which I took to quite a few LAN parties. While I’ve always had Intel notebooks, my PC’s have been AMD for quite some time now. I decided to upgrade my current main machine, which is an FX-8350 with a mild 4.4Ghz overclock. I was using 2x8GB Crucial Ballistix DDR3-1600 and a Sapphire Radeon Fury Nitro. While I know the R5-1600x would be a better bet for a pure gaming build, I have a soft spot for 8-core machines. I had been tempted to pull the trigger on an i7-7700k for a while, but the timing never worked out. But when I found the R7-1700 at a deep discount and an X370 motherboard on the shelf next to it – I couldn’t resist the siren call of a new build.
Here are my thoughts about the process:
AM4 is physically the same as AM3 from a build perspective, except for the mounting holes. I don’t know what was so important about making the holes have different offsets, but this makes it much more difficult to get quality cooling. Not all manufacturers have brackets yet, and I’m still waiting on Cooler Master to release the brackets for my Siedon 240.
The new motherboard feels very different from my AM3 board. My FX-8350 sat on an ASUS M5A99FX Pro R2.0. It was, for lack of a better word, a very workstation-ish board. 4 PCIx16 slots, 10x USB ports (2 of the USB 3.0), triple USB 2.0 front panel headers (and a USB 3.0 front panel header as well), eSATA on the rear panel, beefy VRM and Northbridge cooling, Toslink output for audio, and so on. The board itself is full of tiny components, support chips, and ports. Granted, many of these connectors are outdated (eSATA and USB2.0), and the PCIe is only 2.0 instead of current-gen 3.0, but there is a LOT of connectivity. Few people paired an FX chip with triple of quad-GPU for gaming, but I know a fair number of people used these for bitcoin mining back before there was widespread ASIC support and back then GPU mining was the most cost-effective way to mint cryptocurrency. Extra PCIe slots could be used for dedicated video capture, PCI-based storage, a RAID card, etc... Having 4 full-size slots allows this kind of flexibility. The new motherboard is an Asrock Fatal1ty x370 Gaming K4. It does not feel very workstation-ish at all. It has only two 16x PCIe slots (and when they are both in use they are only 8x), 8 USB ports on the rear panel, and a much less “busy” motherboard. Very few support chips litter its surface. Instead of a workstation component, it feels much more like a luxury consumer product. This is not a bad thing – just something I noticed while building the system. The rear IO shield is red and black to match its gaming aesthetic, it includes things like premium audio (including a very nice headphone amplifier for the front panel connectors), and while it only has 8x USB ports on the back, 6 of them are USB 3.0 and two of them (including a type-C connector) are USB 3.1 gen2. It includes RGB LED’s under the chipset heatsink and three separate RGB LED controller ports (one of which is used for the boxed cooler), Intel gigabit Ethernet, and dual M.2 slots (one of which connected directly to the CPU). It is very different in “feel” from the older ASUS board, even down to things like a shroud for the external connectors and metal-reinforced PCI slots. I must say, its more aggressive appearance and near-empty areas appeal to me. It does, however, funnel the builder into a particular configuration: limited fast storage through the M.2 slots, slow(er) storage through the 6x SATA ports, all external devices should be USB 3. Personally, these limitations didn’t restrict me for this build, since that was how I was going to set it up anyway, but the fewer connectivity choices might cause some pause for others. The only thing I don’t like about this board is the 20 second POST times. 20 seconds every time. Resuming from sleep is very fast, just reboots are slow. That’s really it. I have no substantive complaints other than that – well, and the memory speed limitations – more on that below.
The Wraith Spire cooler is without doubt the best looking box cooler I’ve ever seen. The symmetrical cylinder look, combined with the LED logo and RGB ring are very striking. I can see why many people have asked to order one, though I think for the 1700X and 1800X they are better off without it. I’ll explain why further down.
Initial hardware setup was very easy. I was able to flash to the newest 2.0 BIOS without any hassle using a DOS USB flash boot drive. The 2.0 BIOS has the newest AGESA code from AMD, as well as support for the R5 processors and better DDR4 compatibility. I didn’t want to cheap out on RAM since apparently Ryzen is sensitive to DDR4 speeds for the latency between cores. I bought the cheapest 16GB DDR4-3200 kit I could find (the EVGA SuperSC 2x8GB), for which I paid $115. While I was not able to get it to boot at 3200, I could get 2933 simply by activating XMP, then manually changing the speed from 3200 to 3000. I then tested it with MemTest86 for two complete cycles, which it passed without errors. I have encountered zero memory issues with these RAM sticks running at 2933. Since this motherboard does not officially support DDR4-3200 at all, I figure this is a good outcome. I am curious to know whether anyone has gotten 3200 on this board – that is, whether the lack of 3200 memory on Asrock’s QVL is a marketing issue or an actual hardware limitation – but I didn’t want to spend nearly double that amount in order to get AM4 verified memory (G.Skill’s FlareX), and 2966 seemed fast enough from the benchmark results I had read.
My old setup had a Samsung 850 EVO 256gb SATA6 drive as the primary boot/gaming drive. It seemed plenty fast but it had become too small for my needs, so this seemed like a good opportunity to buy a new SSD. I originally thought the NVMe drives would be out of my price range, but I bought the Intel 600p 512GB drive for only $10 more than I would have paid for a premium SATA6 drive. Though the 600p is without doubt the SLOWEST NVMe drive out there, it has 3x the read speed as the SATA6 drives, and most of what I am doing with it is trying to get quicker load times. If I was using it for professional workloads (as a video editing scratch drive, for example), I would need much higher sustained write speeds and then Samsung would be the obvious answer. I just didn’t want to spend an extra $80 on write performance that I’d never notice, and the 600p has been an excellent boot/gaming drive.
Ok, back to the Wraith Spire. I tend to have bad luck with the silicon lottery. My FX-8350 was not able to be stable above 4.4Ghz with reasonable temperatures. I was hoping I would be able to get better results from the R7-1700, since general reports indicated that it overclocked well. Unfortunately, it is difficult to tell how good of an overclock I am getting since I can find no good information about maximum recommended temperatures for this chip. Some people say 75c is the maximum safe temp. Others say 75c is a fine everyday 24/7 temp. Others say they are running it at 80c all the time without any issues at all. Steve at Techspot was getting 88c and 90c when overclocking the 1600X and 1500X using the stock coolers and without any instability – were those dangerous temps or totally fine? Nobody seems to know. I like my overclocks to be set-and-forget. I want to get it dialed in and then leave it for years without worrying that it will burn up or degrade or that in this or that application I have to turn back to stock speeds because of the thermals. Since I don’t know what max safe thermals are, I just have to guess based on stock thermals.
For stock speeds, the Wraith Spire does a good job. It is very quiet, and after a few BIOS fan-curve tweaks, it keeps the chip around 35-38 at idle, and around 68-70 on Prime95 (Small FFT, for maximum temperature generation). Incidentally, it also hits 70 if I run Cinebench a bunch of times in a row as well, so I don’t consider the Small FFT test to be totally unrealistic for the load this chip might encounter. From what I can tell, these are good normal temps. I can get 3.5Ghz by simply changing the multiplier and leaving the voltage at stock. This gives Cinebench numbers around the 1550 mark (roughly 6900k levels). Prime95 shows a modest boost in temperatures of 3-4 degrees C, and was stable even for several hours. If I push it to 3.6Ghz at stock voltage the system is unstable. At 3.7Ghz (the 1700’s boost speed for single-threaded loads) it is stable only if I give it 1.3v. While that is a totally fine voltage (AMD recommends up to 1.35v for 24/7), the Wraith Spire cannot handle a Prime95 Small FFT load anymore. I shut down the test and reverted the OC when the CPU read 89c. Given the fact that the Spire was meant to cool a 65w chip (and so probably is rated at no more than 85-95w), this is not a terribly surprising temperature – I wish I knew if it was dangerous. I have no doubt that a 240mm radiator or even a decent tower cooler will be more than enough to cool down my 3.7Ghz R7-1700. I am a little jealous of the people who just set the multiplier to 3700 and are good to go – lower voltages probably mean the Spire would be enough. But for me, it was not to be. I was halfway tempted to see at what temperature the chip would reduce its clock speed, but I didn’t want to burn up a chip I had just bought – might as well wait until I get bigger and better cooling to OC it to the 3.8-3.9 I hope it will reach.
Other than the OC temps it has been smooth sailing. Gaming feels more fluid than with the FX, even in games that I always thought were GPU-limited and/or running at 60fps with VSYNC on. Especially games that are sensitive to single-core performance (Heroes of the Storm is my latest addiction) there is a definite boost in 1% low and 0.1% low FPS. I have been using the Ryzen Balanced power plan from AMD and it seems to do a fantastic job keeping temps low when idle and letting the cores ramp up really fast when needed. I need to test whether the lack of core parking prevents it from hitting the 3.7Ghz boost as much as the regular Balanced plan allows. I think a simple CineBench single-thread comparison will do the trick.
I also tried streaming a bit – and it was able to generate 1080p60fps at x264-medium settings without being noticeable while in game. Later I edited some video of my kids – the final render speed was SOOOO fast. I am, on the whole, very happy with my upgrade. I get better single-core performance, much much better multi-core performance, along with faster disk speeds, and a more modern platform (with RGB lighting, M.2, USB 3.1, etc…).
Now if only I could find out appropriate temperatures…..

New people please read this. [upvote for visibility please]

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can.
Preface
Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here.
If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier.
Mining. What is it?
Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section.
Mining Hardware
While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much.
Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it.
So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy.
Should I mine?
Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats

Hardware Fundamentals
CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with.
RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory.
HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats)
GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like.
PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption.
MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less.
PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied.
When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info.
Mining Software
Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head)
Mining Pools
Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself.
How do I connect to a pool?
Most pools will give you a tutorial on how to but the basics are as follows:
  • Signup for a pool
  • Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
  • Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
  • Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability
This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine:
Hardware cost: The cost of your physical hardware to run this whole operation.
Power: Measured in $/KwH is also known as the operating cost.
Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon.
Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously.
Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones.
coinwarz
I like this one cause it is simple. The fields are self explanatory. Try it.
bitcoinwisdom
I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account.
Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it!

My Bitcoin Mining Project and MRIP

EDIT: Everyone, I totally f'd up on GPU's that I would have by end of June. I just wrote a quick VBS script that shows I'll only have 22 (15+7) by end of June. Not too shabby, but definitely not 48. Just wanted to post an update. Feel free to use the script!
So I've posted here a few times in the past. Now I'll detail what I'm doing a little further and try to help others.
Right now I'm working with 5x 7950's, 3x 7850's, a 6750, and 3x GTX 580's (my gaming rig). My hash rate is about 4,500 MH/s. I started this project using the DRIP (http://en.wikipedia.org/wiki/Dividend_reinvestment_plan) principles in mind. I call this MRIP (Mining Reinvestment Plan). The plan is to reinvest all bitcoins mined into more mining hardware. Today I just purchased two more 7950's that are due to arrive tomorrow. Note that these two cards were purchased with bitcoins that were mined. This should bring my hash rate up to about 5660 MH/s, which will let me purchase another card next monday. The plan is every time I have enough to buy another card, I withdraw the bitcoins and convert it into cash. At this rate I'm hoping to have about 48 additional 7950 cards by the end of June or about 33,000 MH/s (33GH/s).
To those I haven't gotten back with about hardware that I'm ordering, I do apologize. I'm using ported 7950's. I STRESS ported cards (ported on top, other on bottom) because they throw the heat out of the chassis. When clustering 12 cases together (4x12=48 cards) it's not ideal to "just leave the side off and hope it's cool it enough". These cases will be slammed up against each other. Going to back to hardware, I still haven't decided on a locked feature set - meaning I don't know what I'm going to buy (mobo, ram, cpu, psu, etc). Ideally I want to keep the core system down to about $70/PCI-e slot, but I have to factor in space (hashing density too).
I say this because hardware pricing is always changing, but I want to lock the specs down eventually because it'll be easy to administer. Having 12 like systems will be easier to deploy than 12 totally different systems (all I have to do is image them). Being a net/sys admin I'll probably administer them with a PXE boot image (which I plan on making that publicly available along with the system specs). Anyways I apologize about that.
I run an IT consulting company on the side and thus I have A CRAP LOAD of old machines with a working PCI-e slot (or two or three). I'll be using these up and then will start building out a system.
Going back to mining, I'm not sure what ASIC's have in store for us. The difficulty could rise so much that by end of June I only have 4 more GPUs instead of 48. My hope is that the difficulty will not go up that high as ASIC's are still very hard to come by and really don't make a good investment case right now (or then). Looking at the difficulty graphs, TH/s seem to be leveling off in the near future - but only time will tell! Let me know if this helps! FYI I have put $0 into this so far, as I've been using old hand-me-down GPU's...
Edit: You all are more than welcome to check out my mining stats!
UltraSPARC_1 = 4x 7950's UltraSPARC_2 = 1x 7950 UltraSPARC_3 = 6750 UltraSPARC_4/5/7 = 7850 UltraSPARC_6 = 3x GTX 580 UltraSPARC_8 = 2x 7950
EDIT 2: A lot of you have mentioned why not buy an ASIC or aren't you afraid the difficulty will skyrocket?! I just don't see that happening soon, and this post makes my case quite nicely. They're even assuming that Butterfly Labs will start shipping in quantity lol
Edit 3: UltraSPARC_8 is online! Two more 7950's, woohoo! I'll post some pictures soon.
Pictures! YAY! For reference please see HERE
My personal accomplishments as of late - Exchange 2010 /w AD deployed recently!
Updates on cards - Because today we saw another pop - I'm planning on buy two (not one) cards by next tuesday. I have about 5 more deprecated systems to use up - thus saving me money - before I plan on locking in a system. Keep ya posted! Thanks for stopping by!
Please note UltraSPARC_6 will be going off line once I get four more cards... This is my gaming rig, and seeing that nVidia "ain't shit" with mining, there's no point in burning up $500 cards...
Edit 4: Just got another 7950 in! Bringing my total hash rate up to a 7,800 MH/s peak! It should settle down though to the high 6,000 range...
Ok, now my mining pool is messing with me. How is this even real?! I mean I'll take the PPS, not complaining or anything!

mining with ATI Radeon HD 5700 series

I have been getting into the bitcoin frenzy finally and started looking into ways in which I can start out. I'm not the usual n00b since I have everything up and working. Only thing that I am having problems with are the performance issues. I have my Catalyst drivers installed and running and the Radeon is working like it should but at a lower speed than I expected from what I have read about others using this same card series. When I use guiminer with the slush pool, I get at least 80 kH/s, when mining litecoin with guiminer scrypt, I get more performance at 200 kH/s. both less than what I had expected. This is all in windows. When I give it a go in Linux with cgminer, the program doesn't even see the card, apparently it seems to be checking the usb hub instead of rhe PCI and PCI express ports. Is there a way to make cgminer look into the pci slots instead of only checking the usb ports. I can always use a USB asic miner from a company like butterfly labs but I have heard not only negative feedback about not only the performance but also the price in which they are sold for and how it's time consuming to get it to pay you back the extremely large amount of money that you spent on them in the first place. Can I get my Radeon card to mine faster in windows, and how can I get it recognized in Linux by cgminer. This is getting really frustrating, and bitcoin jobs are more competitive than actual jobs. If it's relavent, I only get internet bandwith at 2Mb/s which i think is a major contributing factor but I've been told it isn't.

The Anatomy of Genesis Mining Rig

Crypto mania is taking the world by storm! From reaching a combined $600 billion market cap, to Bitcoin trading at $20k on some exchanges, there seems to be no stopping the rise of digital currencies.
There are many ways to cash in on the potential that crypto has to offer, one of them being mining. This is the process where each transaction or record on the blockchain network is verified. As a reward for their contribution to the network, the miners receive freshly generated cryptocoins.
The cryptocurrency mining process is extremely processor as well as power intensive, and can get expensive if tried individually at home. Not to mention, the mining process requires specialized hardware, which has to be set up by oneself along with the power supply to feed the hardware. Genesis Mining steps in here to make the whole process easier, allowing interested cryptocurrency community members to be part of the mining community without going through any of these hassles. On a mission to “democratize mining”, the company is providing accessible and affordable cryptocurrency mining solution to the masses.
Genesis Mining provides cloud-based mining services to small- and large-scale investors. Their mining farms already have all of the equipment set up. In fact, the platform has the best Bitcoin and Altcoin-mining hardware and software available and running already.
The representatives of Genesis Mining have recently taken an initiative through their “EvolveWithUs” campaign to explain cryptocurrency mining and their services in the sector to the general public to increase awareness about the process and the company’s offering.
What is a Mining Rig?
Stefan Schindler, CTO representing Genesis Mining offers a simple definition for the most crucial hardware in the mining operation by saying,
“A mining rig is basically a computer, but is stripped down to the minimum in terms of computing, and up to the maximum in terms of mining.”
The Evolution of Mining
Mining had previously been done on a computer’s processor. However, as the industry grew, so did its mining requirements. Processor mining took an enormous amount of power, and an alternative was eventually adopted — Graphic cards. Graphics Cards or GPUs, proved to be more efficient at processing transactions, and didn’t use nearly as much power, resulting in a classic ‘work smarter, not harder’ approach. Since then the industry has advanced, creating specialized hardware called ASIC miners. However, GPUs still play a vital role in mining some of the popular alternative cryptocurrencies (Altcoins) in the market.
The Structure of a Mining Rig
In appearance, it looks like your average computer mainboard. The key difference is that is filled with lots of GPUs. The USB port contains USBs holding the actual mining software, which is not stored on the processor. It also has plenty of connecting cables to make everything run.
GPU processing
In the case of Genesis Mining, their specialized mining rigs can hold about six GPUs each. The mainboards available on the market do not have the internal space or slots for all of these GPUs that goes into Genesis Mining’s version of mining hardware. This is where PCI risers come in, which are extension cables that allow the mainboard to be fitted with many GPUs. These risers also help with even heat distribution so that the rig doesn’t overheat.
The power supply unit is also fitted with a strong cable, and powers all of the GPUs and the mainboard.
The company manufactures, stores and operates the mining rings at their mining farms in Iceland and other locations. These equipment can be quickly and efficiently assembled and are completely mobile for added convenience.

Building a Dual Rig (gaming and mining)

What is your intended use for this build? The more details the better.
I’d like to build a gaming/mining rig. I would like to run 6 graphics cards at one point, might not buy them all outright. So the goal. A gaming computer running the 1070 separately so I can still game and do stuff while the other 5 cards are mining. When im not using the computer, I have the option to put the 1070 to work as well. Is it a stupid idea to combine the two purposes into one super computer? Also, I’m having trouble finding a compatible motherboard and would love suggestions. Finally, I have tried reading on the riser connection info and I’m still not sure. Hopefully those are the correct risers?
If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)
Nothing too crazy. I have done the research on that side of things and the things selected should make me happy.
What is your budget (ballpark is okay)?
$2000-3000 (depending on how many gpu’s I buy at onece)
In what country are you purchasing your parts?
U.S.A (amazon, here is the link my current list. https://www.amazon.com/gp/registry/wishlist/2NAC9YOHISTRI/ref=nav_wishlist_lists_4)
Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).
CPU:
AMD Ryzen 5 1600 Processor with Wraith Spire Cooler
Motherboard:
Im not sure!
Memory:
Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-3000
Storage:
Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)
WD Blue 1TB SATA 6 Gb/s 7200 RPM 64MB Cache 3.5 Inch Desktop Hard Drive (WD10EZEX)
Case:
Aluminum Stackable Mining Case Rig Open Air Frame For ETH/ETC/ ZCash (Black)
Power Supply:
(2) EVGA SuperNOVA 750 G2, 80+ GOLD 750W, Fully Modular, EVGA ECO Mode
Graphics Cards:
(5) XFX Rs XXX Edition Rx 570 4GB OC+ 1284Mhz DDR5 3xDP HDMI DVI Graphic Cards RX-570P4DFD6
(1) EVGA GeForce GTX 1070 SC GAMING ACX 3.0 Black Edition, 8GB GDDR5, LED, DX12 OSD Support (PXOC) 08G-P4-5173-KR
GPU Risers:
6-Pack VICTONY PCI-E 16x to 1x GPU Riser Adapter 60cm USB 3.0 Riser Flexible Extension Cable & MOLEX to SATA Power Cable,Powered Riser Adapter Card with LED Indicator
Would it also be possible to run a "Antminer S7 ~4.73TH/s @ .25W/GH 28nm ASIC Bitcoin Miner" on this set up if I increased the power suply?
I think it looks decent? But I’m happy to hear advice/suggestions. Thanks so much!

Woah, lets make some special alt-coin servers.. bad idea?

Alright, so I got this idea... I've been making servers for a doctor over the past few months. He's filthy ass rich, I've made him five milk crate style servers (20x 7950s)and hes made over 140,000 thousand usd on litecoins so far. He's given me no cut, and I only made 200 a server from him. It made me mad because college is too damn expensive. Anyway, on to my idea. I've been researching and getting pretty good at making these and running them efficiently. I've also seen how many people showing interesting in the bitcoin world, and they have no clue where to start. Some know a ton software wise, and very little hardware wise. I've also seen how there are absolutely niltch websites that sell alt-coin servers. So lets say I made servers for people who are interested. Put them in crates like these (https://openrigs.com/giorgina-stackable-gpu-frame) and used riser like these (http://www.aliexpress.com/item/PCI-E-PCI-E-Express-1x-to-1X-4x-8x-16x-Riser-Extender-Adapter-Card-with/944387438.html). Preset the OS, and the cgminer. All the user would have to do is plug in and run. The question I have is would people be interested? I know difficulty is going extremely high, but along with the price! As long as the price increases it would stay profitable. GPU's are starting to come back in stock. And with stackable crates like these, its very modular and racks of racks of servers could be made. These new litecoin asics are barely gonna make it. 25MH for 10 grand in parts is almost the same price that could be spent for GPUs. Im not posting an ad, I just want some feedback from this wonderful place of reddit :)

3 rigs, 4x7950's per. Questions regarding System Ram to VRAM, Powered risers to unpowered, and power consumption.

So Like everyone else and their mother I was speccing out a system to bitcoin mine when I stopped lying to myself and came to the conclusion ASIC's will ruin me within two weeks IF they do come out (BFL). So instead, seeing that LTC are going to MTgox in a short while I figure I should mine those while ASIC's aren't in the picture and shouldn't be for quite some time.
Now to the build questions.
  1. How does system RAM factor into LTC mining? All I ever hear is "it matters, but I don't know how much or why" or "You want an equal amount of system ram to the GPU VRAM, but I don't know why" It would help for me to know why I'm doing this.
  2. In what situations do I need a powered x1 to x16 riser cable? From the few sources I've been able to find, they just say it's only needed for GPU's with 2 cores, like 5990's, 6990's, and 7990's. OR motherboards what don't send enough power through the PCI-E slot.
  3. 4x7950's on a single 1200w PSU shouldn't be an issue, correct? @145w x 4 = ~580w @200w x 4 = ~800w for just the cards. I feel like I'm wasting money on that PSU if the total system wattage under full load is so low.
  4. Like everyone I'm going with a 145 semp, the mobo I plan on getting is an ASUS M4N75TD I shouldn't have any problems theoretically with a configuration using two x16 to x16 risers and two x1 to x16 un-powered riser adapters for the other two cards right?
Thank you very much for any assistance you're able to give me. If I had LTC to tip I would.
Brown
Edit: Formatting, and added build below Edit 2: fixed some calculations
7950x1 @ $290 7950x4 (per rig) @ $1160 7950x12 (all rigs) @ $3480
7950x4 @650kH/s ea @200w ea = 2.6MH/s total, 3.25kH/J
w/ 3x4 rigs
7950x12 @7.8MH/s total
Per Rig Cost: ~$1550 ea ~960w total ea = 1.67kH/$ 3.25kH/J
All 3 Rigs Cost: ~$4260 ~2880w
If I can I'd like to make this a bit more power efficient, so if anyone has any suggestions please, let me know.
(I included an additional 100w and $100 into the price of each rig just in case.)

[CANADA-BC] [H] Crypto Currency Mining Enclosure and hardware FULL setup sale [W] $ or Bitcoin

I own a crypto currency mining investment company and I'm selling off the current hardware setup. It has been in use since mid-March of 2014. I've had a series of unfortunate events occur in my personal life that require me to sell off my business's hardware and other personal items.
This is for a firm priced sale, I am looking for a buyer that is either wanting to get into the mining business and wants a GPU based setup that can tackle all the new algorithms VS ASIC based setups that go obsolete within months and have no resale value. Or a buyer that wants to expand their mining farm or mining business and would love a plug-n-play type setup where the only thing they are required to do is have one power feed wired into their warehouse or home panel. This would be for local pickup only most likely. It will require the buyer to have a truck or to rent a u-haul type of moving truck. The system is roughly 60 inches tall by 95 inches long by 24 inches wide, not sure on its weight but moveable if the cards are removed(the cards are designed to be plug-n-play as well, no screws, just pop out pop in.) and runs at 240v for PC hardware and 120v for fans/misc regular appliance plugins(routers/switches etc).
The enclosure houses 8 systems which consist of 46 R9 280x video cards (it has room for expansion), has its own built in surge protection system to withstand lightning and other outside-the-enclosure based surges, whole system runs at 240v for best efficiency, has a 100amp breaker panel which is attached to the enclosure for maximum expansion.
The enclosure has 6x20 inch box fans which provide the 24/7 constant air flow for the video cards. I have two other 20 inch box fans that are for in and out airflow for fresh air circulation. All video cards are easy to access and can easily add or remove cards to/from the unit. I built the enclosure design in-house.
Serious inquiries ONLY, I have priced this as fair market price for used hardware among the enclosure costs which include the power panel, surge protection, cable runs, professional electrical hardware/electrician fees etc. This is a full plug and play type enclosure setup for any mining farm out there. Originally built for $33000~, I'm strictly selling it at a fair hardware priced value with cutting out a lot of the fee's that you would have to pay for an electrician to wire up your own custom enclosure and the electrical hardware. Cash or Bitcoins only.
Asking $15000 Canadian firm. Also I am located around Vancouver, British Columbia, Canada.

Both rigs runs Windows and comes with the installation disc (Dell branded), but I was running a live Debian-based OS from a USB drive that will be included (4gb). It supports litecoin and bitcoin, and even the USB ASIC block erupters. It has remote monitoring support, which is mainly why I used it.
Will accept litecoin, bitcoin, Paypal, Dwolla, or Wells Fargo transfers. I would rather not ship outside the USA or part out. If no one is interested here, I will likely just list them on eBay.

Jet - $950 / 1.9 BTC / 950k DOGE - 2x Sapphire R9 270x GPU - Motherboard, CPU+fan, 8GB DDR3 RAM - 1x USB Powered PCI-E 1x to 16x Riser - 1x 40 GB SATA Hard Drive - 1000W PSU - Open air black metal frame - 880 kh/s Scrypt Mining on cgminer
Sorry but prices in BTC/DOGE are subject to change, I have to pay USD for all of the components here so I have to adjust for the exchange rate. Prices quoted here reflect the current exchange rates and will have to be recalculated if there is significant gain or loss of value on the markets.
Both rigs are mining away at the moment with cgminer 3.7.2, so if you want them they are basically plug-and-play, just need to be configured to point at your pools (which I can show you how to do if you are a newbie). Windows 7 is the 'trial version' so it will ask you for a validation code but it will run just fine without it. I am also willing to build and deliver fully working CUSTOM MINING RIGS at various hashing powers - 800, 900, 1200, 1500, and 2200 - for around $1.25 per kh/s (with payment up front).
Professionally I am a career educator, so I am very patient and willing to sit down with you if you are unfamiliar with crypto and explain how everything works. I will make sure that the miner I sell is configured right and ready-to-hash, and I will explain to you how to use it and how to keep it running right. I have mined scrypt coins on several different types of cards using both Linux and Windows OS, I have mined BTC using ASIC hardware, I have managed exchange accounts, qt-clients, and a futures account on ICBIT. So basically I have some knowledge and expertise I am willing to share with anyone who is interested and willing to invest some money with me for hardware.
I think that GPU rigs are still a very good investment in crypto for two reasons. At the moment the scrypt coin economy is pretty stable. 1,000 kh/s will get you the equivalent of 0.010 - 0.015 BTC/day depending on which scrypt coin you choose. There are several coins that give at least this good of a return, which is great on its own. But then add the fact that GPUs can be resold for a very good portion of the original value, and that a mining rig can be re-purposed as a workstation or gaming rig. Personally I think I can offer a really good value, and if my apartment were rated to deliver more electricity without overloading my circuits, I would be building and mining off of more cards myself.
I am also willing to buy/sell limited amounts of cryptocurrency in person - up to $1,000 USD. I have well established accounts on major exchanges so if you are looking to buy or sell without all that hassle, I can help you out.

[Build Ready] Bitcoin/Linux/Windows build (noob here, helped by a pro)

Hey guys this is my first build but my friend helped me so everything should be in order, I just want a sanity check:
http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=11967569 (I'm also saving about 70$ from Newegg promos)
Monitor: http://www.ecost.com/p/LG-Electronics-Monitors/product~dpno~8256700~pdp.gcidgfd (I already have 1 23inch monitor but it is not LED backlit and I don't have access to it until late August)
Graphics Cards: Two Sapphire Radeon HD 5850 XTREME are already in the mail
Reaoning: I plan on running some flavor of linux as my main OS (probably Arch Linux). Windows 7 will run either concurrently with Xen Hypervisor or in a Virtual Machine -- occasionally I may boot into Windows 7 for games if I can't get graphics card access through the hypervisor).
Additionally, I will be mining bitcoins with the two GPUs most of the time (whenever I am not using them for anything else). I plan on putting the HDDs into a RAID array (I'm even sort of considering a 4th one since they are so cheap).
I am a either double majoring or single majoring in ECE and/or CS and plan on using this to compile and manage large projects and possibly run resource intensive programs.
I tend to be lazy with my tabs and I don't like closing programs (I need a lot of RAM -- also running two OSs will take RAM)
I have three points that I'd like others' opinions on (other than an overall sanity check).
Case: Can I fit everything in this case (without a big risk of heat problems)? My friend definitely thinks so, but I just want to make sure. I would rather have the mid case.
PSU: If the bitcoin market starts to become really profitable again (like where it was a few weeks ago) I will probably get a 3rd GPU and possibly that bitcoin miner ASIC that's supposedly being released in Q4. In my wishlist I currently have an 850Watt PSU but I'm actually leaning towards the Cooler Master 1KWatt PSU now
Monitor: Do you think there is a huge risk getting a refurbished monitor? If so what 23 inch LED back-lit monitor would you recommend?
Thanks for your help!
