Building a six GPU Ethereum Mining Rig

I have been working with blockchains since 2013 but always wanted to know more about how the mining process worked. Last year, I fell in love with Ethereum and was excited to learn the project uses a GPU friendly algorithm. I convinced my wife to allow me to spend some money to build a GPU mining rig. At the time I built the rig, I calculated it would take over a year to break even in mining Ethereum. Luckily, the Ethereum project has taken off in a big way. The rig paid for itself in a few months, and continues to deliver. I had a lot of fun building the rig and learned a lot about how Ethereum works in the process. My rig does about 160 million hashes a second and dual mines Ethereum and Decred. Here are some details on the setup.
