1. The Thermaltake liquid cooling set up is completely cr@p. The case is pretty decent however.
2. The CPU cooling alone will cost you ~$250 or so with top of the line stuff. About $150-200 for the GPU loop (assuming you'r using the built in block).
3. WHY would you get the GTX480? Imo, it's over priced and runs too hot (with out WCing that is).
4. Don't bother cooling the chip set,RAM,etc.
