What Tom's didn't tell you is that these things are junk. The power supplies are small and can't be upgraded, the case can't hold a double-width graphics card, using multiple hard drives will usually result in one overheating (eventually), and you can't even mount a TV-Tuner card and sound card in the same case. If you ever wanted to upgrade the motherboard, good luck.
