To build a bitcoin mining machine, you must first understand what it is. Primarily bitcoin mining can be considered as a giant lottery where you compete with other miners to earn bitcoins. Faster hardware can make more attempts per second to gain bitcoins while the bitcoin network adjusts itself continuously to keep the rate of finding a winning block has to every ten minutes.
Think of a Bitcoin ASIC as specialized Bitcoin mining computers, Bitcoin mining machines, or "bitcoin generators". Nowadays all serious Bitcoin mining is performed on dedicated Bitcoin mining hardware ASICs, usually in thermally-regulated data-centers with access to low-cost electricity.
There are three machine models in the Fast-Hash One series of Bitcoin mining machines: the Silver Edition, the Gold Edition and the Platinum Edition. These are 19" rack mountable Bitcoin machines, with the main differences being their expandability and the power of the included mining modules.
Bitcoin Mining Hardware Guide The best Bitcoin mining hardware has evolved dramatically since 2009. At first, miners used their central processing unit (CPU) to mine, but soon this wasn't fast enough and it bogged down the system resources of the host computer.
Bitcoin mining difficulty has accelerated so much with the release of ASIC mining power that graphics cards can't compete. If you do want to use them, you'd best equip yourself with a motherboard that can take multiple boards, to save on running separate PSUs for different boards.
