Looks beautiful but the Psu is a bit overkill for this unless you populate it wth Gtx 1080 ti cards. In fact I think that would be the most effective cost in long term as I am sure bitcoin price will go up. Unfortunately 1080 ti is still very expensive on the market. There are cheap miners being sold on ebay and even with a cheap price no real demand is seen. I see those ads from a long time now. I have bought one from there and I am happy with it.
