Corsair closed loop cooling - already have it
In about 6 months I'm going to add a second video card, maybe an asic card if bitcoin continues to take off, and do a custom water cooling loop. This will be my first attempt at custom water cooling so that's why I went with such a beast of a case. I'll also be getting a g-sync monitor. Hoping for a 4k 27"ish. I think they showed off a few at CES.
Without increasing the current price, alternate parts? I don't want to sacrifice performance.
