Its a Dell dimension 5100 with XP preinstalled, was going to keep the P4 2.8ghz processor thats in there for now until i can afford a new one. Got a saphire 4670 512mb card in as well.
What i was after is something like an idiots guide to changing boards - when to uninstall old drivers, how to handle the BIOS, reinstalling XP (or replacing with vista) etc.
Cheers for the help,
Andy
