Nice rig, man!!!
I dream about such amount of GPU's))
Just started mining 24 hours ago with my 1070 and making plans for future to buy 1 more 1070 and 6 rx470. But i have a problem - here in my country prices are very high and salaries are very low)) But i will figure out how to solve this i think!
