We do not recommend using laptops or all in ones, like iMacs, as they are very closed systems. It is harder for them to dissipate heat and they are more difficult to repair. While we don’t have any experience building mining rigs, we found this guide with template builds. The general goal is to get multiple powerful AMD graphic cards with bare-bones everything else (to reduce electricity costs). Here is a comparison of specific card performance. Thanks to the mining craze, you will have to pay top dollar for the popular cards (if you can even find them in stock) but this site may help with your search. Needed to get the OS and program running. Comes in two forms: integrated and discrete. Integrated (ex: Intel HD) means it is built into the CPU. Discrete (ex: AMD Radeon or Nvidia GeForce) means it is separated from the CPU so it can be more powerful.ĭiscrete cards are more effective at doing the mining calculations. Temporary data storage (data lost if power is cut). Communicates with the CPU / GPU faster than permanent storage can (system would be bottlenecked in speed if it tried to only communicate with permanent storage). Required just for the system to function. Go for minimum viable specs for low electricity usage.Ĭonnects everything together and sometimes has ethernet or wifi built in. More PCI express slots on it means you can attach more GPUs. Used to save data even when power is turned off. Usually in the form of hard disk drives (hdd) or solid state drives (ssd). SSDs are faster and have no moving parts (better), but are more expensive. Go for minimal power usage with enough storage for the OS and mining program.Ĭonverts the power from the outlet into a more regulated form for the computer parts. Ensure you pick one that is high quality to protect your expensive GPUs (unexpected surges can damage your hardware). Higher efficiency = less electricity wasted. You also have to buy one with a high enough capacity for your rig. Includes wi-fi cards, monitors, keyboards, mice, and other add ons. Mostly not needed for mining beyond initial setup. Wi-fi / ethernet are sometimes built into the motherboard. Hardware enabling an internet connection IS required. You can also mine with virtual servers (such as Amazon EC2), which have no upfront hardware cost but bill by usage. However, they are more difficult to set up and we do not think these are cost effective anymore (better to just buy Doge outright). In fact, a shibe named Grant Ammons wrote up his experience losing money.
