The Thermaltake Rhythm HTPC Liquid Cooling System has taken the formerly extreme art of water cooling and made it feel right at home in an HTPC environment. The extreme cooling and extremely low noise output are welcome features in a home theater personal computer, and will help insure that your system stays up and running without you having to hear that it is doing so.
