Dude, that is just so cool!
Most of these contest computers (Gaming Tribe's recent contest, Corsair's recent contest, etc) have one or two cool things, and the rest is like "if I won, I'd tear that out and replace it with...", but going through this one, I don't think I'd tear anything out (with the exception of replacing the H105 with a custom loop), I'd actually add onto it.
Sweet build!
