A little bit of everything, but right now it's more of a proof of concept.
Probably going to be a media system of some sort in the future. With six NICs, 802.11ac, and Bluetooth it should be able to connect to things pretty easily. Once I get a job I'm going to have to decide if I'll be adding an RX 580 to it or replace my 980 Ti with Vega in my workstation and put the 980 Ti in this thing. And water cooling the CPU because the air cooler the board came with is almost worthless.
