The entire waterblock is copper with a see-through acrylic cover. The copper combined with the shiny acrylic is just gorgeous. The overall design of the waterblock is well done and aesthetically pleasing. Four screws securely attach the acrylic cover to the copper base. Two barbs are centered evenly for a symmetrical look. Under the screw down caps are 5/16in prongs to attach the tubing. Between the barbs you can see the pathway for the liquid cooling. In the right hand corner you can see the small LED encased in the acrylic cover. The LED is blue to light up the entire block. This waterblock is universal; with the included clamps it is designed to fit Intel P4 socket 775, P4, AMD K8, and AMD K7.
