The only question I would have would be about the motherboard and the Duron 1.3g cpu. Since it is a older 761 motherboard, will it need a bios flash to use that newer cpu. A look at the motherboard manufacturers website would tell you the answer.
Oh yeah, and 128M ram isnt enough, itll be a little slow with just 128...especially if you try to run WindowsXP.
