I have a full Danger Den water cooling set up for the Athlon 64/FX/Opteron that I will not be using. It contains the following:

Aluminum 120mm Silver fan
120mm Black Ice radiator
Clear 1/2 inch tygon tubing
Typhoon Dual 3.5" bay reservoir (UV green)
RBX waterblock for Athlon 64/FX/Opteron
Swiftech MCP600 water pump (185 GPH)

At the time I had bought it for El Diablo, but will not be using it. I thought about making an adapter from plexi and using the set up for R2-D2, but have decided to use and Phase change cooling system. Originally it cost $325. It yours for $200, paypal only.
