My PowerMac G4 Quicksilver, dual 1GHz processor has died, the logic board is blown and most repair places say it's not worth it to fix, especially when the boards are no longer available new. I agree with them, I got seven years out of it, it's time to upgrade. So I'm looking at used G5s, but to save money I want to salvage as much from my G4 as I can, like my 160Gb hard drive, the three 512 sticks of RAM, plus a USB 2.0 card I put in some time back. Are these pieces all compatible with the G5 units, specifically the dual 2Ghz model M9455LL/A? I'm not finding a lot of info, I can order the G5 stocked with this stuff but it's nearly twice the price, and I'd hate to toss the good parts I already have. Anyone?
