When Ethereum exploded in popularity (and value) in Summer of 2017, I
decided to educate myself about cryptocurrencies and blockchain technology. As
part of that process, I built an Ethereum (Classic) mining rig.
Here I'll discuss how I designed and built my miner, focusing primarily on the
construction of the chassis using OpenBeam, Fusion 360, and
a Shapeoko 3. (Later, I'll discuss BIOS configuration in Part 2,
mining strategy optimization in Part 3, and compute performance
optimization in Part 4.)
