Head over to
DangerDen to find a selection of parts, this is what I would recommend:
TDX (Silver if you can afford it)
Black Ice Extreme 2 (or just the regular if you dont have room for it)
Vantec Stealth Fan (if your going for silence) or some kick ass fan like a delta screamer
Tubing (tygon will work)
Distilled Water (from your local grocerie store)
Zerek Racing Coolant (From the Den helps with heat transfer)
