PowerMacs just seem to end up at my feet these days. I recently acquired another iMac G3, and yesterday got two PowerMac G4's for $20. What should I do with these extras? BTW I already had a PowerMac G4 (used as a home server) before I got two more yesterday, so what should I do with these extras? I already use one of the iMac G3's as a kid computer (the one with a non-functional Ethernet port), but what should I do with the other one? EDIT 1: I would like to upgrade one of these PowerMac G4's and use it as an old gaming rig, but the upgrades are so expensive! Just look at these prices: RAM: 2GB PC100 (512MBx4) RAM $80 (cannot find 512MB RAM sticks for less than $20 each) Processor: 1.6GHz (single) $160 (cheapest processor upgrade I see for the Sawtooth) Graphics Card: I don't even know what options there are. (Help?) Is there any CPU upgrade for the PowerMac G4 "Sawtooth" that isn't ridiculously expensive? That's the most important thing... I already have 1GB RAM, so that's not too much of an issue.
