Hello everyone, I love my 15" iMac. It's beautiful. It's practical. I just isn't very peppy. I know I can't upgrade the processor because it's soldered to the logic board. So I had a crazy idea. Can I take a 1.25Ghz logic board from a 17" iMac and use it in my 15"? My knowledge of PPC iMacs is lacking, so i don't know if the board will physically fit or if all the cables and connectors will work. I won't destroy a working 17 iMac, I'd buy a replacement board online. That would be wrong. I know I could just buy a faster iMac, but that wouldn't be as fun. Thanks!!
