Or the SP35P2 for that matter?

What cooling kit did you install?
I think this would be a nice mod, but I'd like to see pictures of how the radiator heat is sent out of the case, and how the 120mm fan is installed.
I just purchased parts from different places. The CPU block is visible, from DangerDen, but with a custom ordered lucite top to fit the mounting dimensions of the Shuttle motherboard. The original ICE mounting screws work perfectly, but with small rubber O-rings instead of the big springs. Tygon tubing is 1/2" ID, 3/4" OD, and I have a few feet spare feet. GPU block is a Polar TT, I think, and it was easily mounted to both an ATI 9700 and later a 7800 GT (@640MHz). The GPU water flow is perfect because it is pumped from above the block, forcing the water into the deep channels, then sucked out the side. Also, the order of cooling components is ideal: radiator, pump, cpu, gpu.
The radiator heat it blown out the top of the case from the fan mounted directly on it. I cut a blowhole in my top directly above the radiator. Even though the radiator is in the top-rear drive bay, I still had a pair of Raptors running in this system, so the internal drive bay is NOT occupied with water cooling gear. For the drive up top, I used a thermally conductive material to transfer the drive's heat directly to the external cover.
