Yeah, i have a dell xp computer. I would like to rebuild it, for my parents will pay for my birthday. I was reinstalling XP when my sister blew a fuse, messed up the instalation, and blew the hardrive. So I was going to buy a new hardrive when thinking, hey, why not rebuild the whole thing. I would like to know the main things i would like to upgrade, and the things i can keep from the original computer. Thanks guys.
