If you're looking for a cheap PC, maybe think about looking for a refurbished model online. It's a pretty simple process: Someone orders a PC, they open it up, call back and say "It's broken". The "unfit" PC gets sent back to the manufacturer, who then pass it on to a refurbisher who just replaces the broken component, restoring it to factory quality. Then they sell it on.
For some reason, this makes it a lot cheaper. It's like manufacturers seal the original box with solid gold or something.
Apparently
Dell Outlet is quite good, but I was told that in 2006...
