Why settle for a regular system with a noisy CPU fan when you can build one that is cooled by water? Who cares that if one of the pipes develops a small leak and gets on your active computer parts that you are basically screwed? In any case, if you like living on the edge this is a good article for you.

Our goal was to run current-generation 3D games as smoothly as we could, with as much eye-candy as possible, and at high resolutions. However, we also had some sub-goals. One goal was to build a fairly quiet system. The idea of having a half-dozen case fans creating a small tornado in our office was less than appealing. A second sub-goal was to take some tentative steps into the overclocking arena.

Last time I overclocked was in 1999 when I needed to.
