I have my hex core up and running with the parts listed above. I used a Lian Li D600 Black case with a water cooling setup (vertical 360mm radiator) for the cpu. No crazy OC's just some mild adjustments. Now here is where it gets fun.

A couple days later with another processor (4820K), 3 gtx-670 FTW (from other machines), I have another gaming machine for the front room of the house.
