The MCW5000 water-block is an extreme duty liquid cooling solution for high-end microprocessors. It is designed to be used either in straight liquid cooling configuration, or in conjunction with a thermoelectric cooling element. I'm looking for $40.00 shipped. Will include Arctic Alumina Thermal Compound for installation. Thanks for looking.

Features:
Extreme performance: 1/2" OD tubing for optimal flow rate
Core Technology: Patent pending Diamond-Pin Matrix© copper base plate for optimal heat transfer, and turbulent flow!
Plug-and-Play, Hassle-Free Installation: Snaps directly to AMD® socket 462 retention latches, without removing the motherboard. Tool-free quick-connect fittings built into the block. Convenient 45° orientation of inlet, and outlet helps eliminate kinks in the tubing installation.

Specifications:
1/2 thick CNC machined copper base plate
Blue anodized aluminum housing
Hose connectors set at 45 degrees to reduce kinks
Outer face is lapped flat to 3/10 of 1/1000", and mirror polished.
