Also, Dell is fairly notorious for using PSUs that are just barely adequate for the system as originally configured. if you are going to try to upgrade/replace parts in that system, I'd consider getting a g33 based motherboard (intel dg33tl or equivalent) with a low end core2 chip such as the e2200, along with 2x1GB ddr2 533 or whatever. this would give you a system many times faster than the celeron 2.4ghz of the original, faster but similar onboard video, etc. you may end up needing a new PSU for this, but this combination would work with a very modest pci-express compatible PSU fwiw, my current main desktop system is a DG33TL mobo + e8500 cpu + 2x2GB ddr2 800mhz, and its a seriously fast and stable system
