My Q9450 and 2x 8800 GTXs are on water, a swiftech 350 pump, $65, a pair of koolance gpu coolers ($85 ea), and now 3 x swifty 120 radiators, at $30 ea, along with 10 barbs($30), and $5 worth of worm clamps. Add in another $10 for 14' of tube and you have it. The cpu block, the swifty apogee gt was picked up for $35.
