Wow, I love jumpers. I didn't realize that the "Do not remove" sticker meant THAT much to Apple. I would have overclocked this thing ages ago. I got ahold of my second Power Mac G3. My first one was a Rev. A 400 Mhz one. The second one was a 350 Mhz Rev. B with two hard drives and a Super Drive I popped into it from a dead Quicksilver. I just popped the G3 400 Mhz CPU into my Rev. B machine and overclocked it to 450 Mhz. I'd like to get some more CPU power but all of the upgrades are G4 CPU's or REALLY high speed G3's. (900-1000 Mhz) I've found some 450 Mhz G3's on Ebay and I was wondering if I could clock those up to 500-550. PCI Extreme would be nice too once they get it working with 10.4.3 and I get a Radeon. I wouldn't mind adding some fans and painting my case either.
