So, what hardware do you need to mine cryptocurrency? OK, the "rig" is essentially a customized PC. Where things deviate from the norm is when it comes to the graphics cards. A lot more. In fact, you can think of a mining rig as a relatively cheap PC with one or more high-performance GPUs attached.
You need to connect multiple graphics cards to a single system, which means you also need a motherboard to handle that. The Asus B Mining Expert is a beast of a motherboard, capable of having 19 graphics cards connected to it. Asus has published recommend GPU layouts for , , and card for this board, and while other layouts might work, I recommend staying with what the manufacturer suggests, as veering away from this is a recipe for a serious -- not to mention expensive -- headaches.
This quad-core Core i5 is perfect for this setup and works great with the motherboard chosen above. SKILL fits the bill. Also: Best external hard drives. Depending on how many graphics cards you have installed, you may need multiple PSUs. These Segotep PSUs are middle-of-the-road good value, yet they offer reliable performance.
This six-pack of powered risers are great and provide stable power to your graphics cards. I do not recommend using non-powered risers. Loads of potential for overclocking, stable, and great cooling.

Most recent gaming motherboards from top-tier manufacturers like Asus, MSI, or Gigabyte will suffice here, although check the documentation to see how many graphics cards the hardware can handle. Keep in mind that some BIOS adjustments will be required to maximize stability with more than a couple of cards. While a hand-me-down gaming motherboard should be sufficient for a starter rig, serious enthusiasts use boards made for mining, such as this Asus B Mining Expert that supports a crazy 19 GPUs.
More serious cryptocurrency hobbyists use dedicated mining motherboards that have pre-tweaked BIOS settings and the ability to connect over a dozen GPUs. But supply and demand issues are a recurring theme with mining rigs, and the boards that support more than six GPUs are often out of stock or seriously overpriced. This is how you get half a dozen or more double-slot sized GPUs to fit on one motherboard.
Celerons, single-stick memory configurations, and other money saving shortcuts are all fine here. This is a perfect place to use items off the spare parts shelf. Dust off that dual-core Celeron, puny Pentium, or Ivy Bridge antique. They all work just fine in a mining rig. But check this listing to make sure.
Be wary of second-hand cards formerly used in mining rigs however, as the stress shortens the lifespan of the hardware considerably. One area requiring investment is the power supply. Typical multi-GPU cryptocurrency setups require plenty of juice, more than even a high-end gaming system, and these PSUs will cost you.
This Corsair HXi has the capacity for several high-end graphics cards. Something else to keep in mind with power use is your power circuit. Most US homes come with 15A circuit breakers, which means a single circuit will top out at around W. Good news: you may be paying a premium for a graphics card and a high capacity power supply, but you can cheap out a bit when it comes to your system memory and storage.
Building your own cryptocurrency mining rig is no harder than building any other custom PC.
