Dont know if your MB can handle this but for an extra 375-450$(depends on if you up your processor) you can change that to this

1024 mb ram ddr400
AMD athlon 64 processor 3200+ 2.00 GHZ
Nvidia 7900 gs 256mb
This would be incompatible with the motherboard.

If you want to upgrade Caius you may as well buy a whole new machine, as by the time you've finished you'll probably only end up with the original monitor, keyboard and mouse and not a lot else.
