I think you guys are dismissing this system too quickly. It has a large two fan radiator, and two slot pump/reservoir. The radiator/fan are not in the 5.25 slot insert. The overall design seems to fit well with the current Cooler Master cases (I have a CM690 sitting next to me and it looks fine) and with that radiator, probably can handle the load of cpu and two 8800GTs. Both Koolance and Cooler Master list units for those video cards, however, like with this kit, I haven’t seen them anywhere to actually buy.
I kinda like the Koolance units because of the SLI bridge tubes and interesting RAM cooling. Koolance also has a 2x120 radiator and combined pump/reseviour/control unit for 5.25" slots...so you could assemble the same unit there. They even have a kit with a 1x120 radiator rated at 400w. However, wouldn't that be rather marginal for a OC'd Q6600 and two 8800GTs?
