I know. In which case, use the second set of links. That would upgrade your Dell. The first set of links would basically replace the Dell, only reusing your CPU, Hard Drive, etc (basic components). It was just a thought, as I wasnt sure if the Dell's case was large enough. When you asked a week or so ago about a video card, it was a low profile card, thats why I wondered if you might have the smaller "desktop" style case, and would benefit from the larger "tower" style.
