Nice and clean setup there!
I'm trying to build my rig up again, Q6600, DFI mobo, 2 GB Corsair, 8800GT 512MB, Antec 500W, Aqua extreme MP-05 (thanks pH!) hehe, MCP 655, MCR 220 with two NMB fans. Made up a top so I could use a danger den TDX on my 8800GT and I'm working on a north bridge block so I should be totally water cooled soon
Maybe even PSU blocks (I'm thinking of some aluminum pipe braised to the stock mosfet heatsinks since there isn't too much heat)
