I am thinking of buying from a friend a G3 to use as an iTunes server. He isn't quite sure what model it is, but it is one of these: The Computer It is one of the G3's in that form factor, with that one thought to be it. I would upgrade the hard drive and RAM, but I do not know to what levels, (e.g. 250GB Raptor SATA drive and PCI card? 80GB ATA?). He wants $20 for it. Does this sound like a good deal? What other uses could this G3 serve instead of just an iTunes server?
