This is my 6 GPu mining rig working on ethOS at 166.7 MH/s

Which brings me 0.1 eth per week is on average 250 euros per month (the price of the ethereum is currently 1Eth = 650 $). My electricity consumption of 900 / h is 70 euros per month to deduct 250.

Simple construction of the frame with perforated angles bought in a hardware store.
I used screws M4 and M6, the bottom plate can be PMMA or plexiglass. I personally have a fiberglass reinforced panel

Some junction parts are printed in 3D on ultimakers. The cards are inclined at 45 ° for optimal airflow and a out of the box design. The cards stayed at 65 degrees each, the speed of the fans is between 17% and 33%. Which allows me to put the rig in an office.
