That's a pretty nice build! I like the clean openness of the case. I cringe when I see a case that's just a mess of wires and ill-placed tubing.
I just finished...or rather finished the base of my build (still more to throw at it) and I went with a NZXT Phantom case. It is monstrous but it's got all kinds of room for working in and expanding.I suppose I should submit my build log but I only just got this thing up and running and I'm itching to overclock once I know it's stable with all my applications running.
Like your build a lot...congrats on your finished work so far!
