I originally built this mining rig back in December 2017 (during the golden days of crypto), I've unplugged this rig from electricity since September 2018, but I might turn it on again in 2019.

Today's article is the second and final part from the series I started back in 2017, see Building a 12 GPU Ethereum Mining Rig From Scratch - Part 1: Ordering Details

The total cost for this rig (4 GPU's with hashing power of about 60 MH/s) was about $1,300. I never break even. To do so ethereum should reach around $5,000 per coin (still hold minned ethereum) To Break Even My GPU Mining Rig, Ethereum Should Reach $5,153

With this rig, I've mined ethereum, expance and ethereum classic using simple mining OS

Before building my first mining rig I experimented a lot with mining at our office computer with cheap Radeon GPU, see Learning Crypto Currency Mining The Hard Way

In total it took me some 3 shipping to get all details, luckily I managed to get them all in about 3 weeks

In above I have mounted EVGA 1060 6 GB and Sapphire TX 560 4GB

Despite I could mount up to 13 GPU's on this ASRock motherboard I never mounted more than 4.

Attached some old monitor for graphics interface, added a cheap keyboard. Connected to the internet via wire through the router. 

Now, despite I haven't broken even my initial investment (and I doubt I ever will) - it was a great learning and experimenting time. No regrets of investing here, as now I feel much much more educated on crypto and crypto mining. During the time this rig was operating I learned a lot on fine-tuning graphics cards and even set up a trading bot on VPS.
