If you're new to liquid cooled PCs it may be comforting to know that even one of the biggest names in computer retail offers a liquid cooling solution. The Dell XPS line of computers was designed with PC gaming in mind, and has evolved its supported technologies throughout the years. With liquid cooling becoming extremely popular, and almost verging on "mainstream", it makes sense that the manufacturing giant would want to tap into this market.
The Dell XPS 730x H2C is truly a monster of a gaming machine. It supports the latest core i7 Extreme Intel processors and has built-in overclocking features. Customization options allow you to choose things like amount of memory, video card(s), and storage.
The liquid cooling system in the XPS 730x uses Dell's proprietary H2C (H2Ceramic) which is a hybrid cooling technology using liquid and thermo-electrics. It is one of the most advanced cooling technologies available today.
