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. There's a small corollary here, and it's that CPU mining of certain algorithms is still potentially profitable. You're probably better off buying another graphics card rather than worrying about CPU mining potential.

Right now they're expensive though. 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. A gold rated power supply is minimum, since mining rigs run at constant high loads, and depending on what GPUs you're running and how many of them , you'll want at least a W output, if not more. This Corsair HXi has the capacity for several high-end graphics cards. You'll need all the efficiency you can get.

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. If you're thinking about setting up multiple mining rigs, you'll need to keep them on separate breakers.

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. Likewise, the speed of your OS drive isn't important for mining. If you have an old hard drive or spare SSD around, that'll do the job just fine. If you're picking up a fresh part, grab a small SSD on the cheap.

It'll make the system easier to use, and you don't need much storage space to keep your mining operation running. You only really need 4GB as there's not much going on in the memory-use front. Building your own cryptocurrency mining rig is no harder than building any other custom PC. It's a great way to learn the inner workings of the hardware, and save some money over a prebuilt system outrageous graphics card prices notwithstanding.

But if you really don't have the time to build your own mining rig, buying prebuilt is always an option. But should you buy a prebuilt desktop PC, or a dedicated mining rig with multiple graphics cards?

Thanks to the cryptocurrency boom, the latter cost thousands of dollars on Ebay, both used and new. Buying used could net you heavily worn graphics cards with diminished lifespans. Either way, it's a huge investment if you're just getting started with mining. For a more traditional prebuilt system, you'll be stuck with a maximum of two GPUs by default, and even prebuilts have been hit by the current GPU shortages. And if the mining thing doesn't work out, you've still got a bodacious gaming PC. But is at-home mining worth it?

Do you have cheap power rates? Hardware laying around? While it is an expensive rig, the build quality and potential profit makes it a very tempting choice if you're serious about mining.
