Dell XPS400

In March of 2006, RF Cafe upgraded its computer from an tired old Compaq to an powerhouse Dell XPS400 desktop system. This baby sports a liquid-cooled CPU (Intel® Pentium® D with dual-core technology). The only thing I am not happy with is the 19" flat panel (LCD) monitor, which is nowhere near as sharp as the ones sitting on the shelves in the stores with other systems. Dell has no interest in replacing it, so my opinion of Dell has been decreased a bit. We have an Inspiron 6000 notebook computer with a 15" screen that is almost as clear as a CRT, so the 19" LCD is definitely poor quality. Otherwise, though, this system screams.
