I built this exactly one year ago but didn't find the time to put online... What a pity! It was top of the range... now already overtaken in several ways.
However - I'm still very pleased with it and I built a whole 3.3 meter custom desk around it. Can't help but showing pics of this as well.
Motherboard: Originally I had an Asrock X399 Taichi motherboard but it fried after 6 months when I enabled CPU + GPU rendering at the same time (VRay). I sent it back to the manufacturer and they sent back a new one (after 3 months) which I'm selling on ebay atm. Therefore I got the MSI X399 SLI which works also very well. Only thing it doesn't have WiFi on board - but that's okay.
Will write a bit more later - short on time again :-/
