I see a few things that I find not too desirable with this kit (besides that mounting bracket that Mike noted). First, the radiator is all aluminum and you have to run some kind of antifreeze mix (which I'm sure that the included coolant that Thermaltake provided contains) or you will have corrosion due to ionic transfer between dissimilar metals. And the pump, while adequate, is not a real powerhouse. Finally, I find a single fan radiator, while easier for mounting purposes, is a bit small for overclocking a quad based system. For the price this is selling for ($135 at the Egg), I would rather spend another $5 more and get the Swiftech H20-220 Compact CPU Water Cooling Kit. With the Swiftech kit you get a double fan brass tank and tube radiator, radbox for mounting the radiator externally and a waterpump/waterblock combo based off of the Apogee GT block and MCP350 pump. There's nothing really bad with this Thermaltake kit but it's competing against a superior Swiftech kit in it's price range.
