I have got a Fujitsu Siemens computers that I bought back in 2002. I want to utilise the case and replace the motherboard processor RAM etc. Somebody recommend me a half decent board, processor and maybe three gigs of RAM that will fit in this case, quite a big case I might add. Also, while I need a new fan and power supply?

If you know a good bundle for a reasonable price, please list it for me
