I got leopard for christmas and i was going to install it into my iMac but come to find out i don't meet system requirements. I have a G4 flat panel iMac w/ 800 MHz and 256 RAM. Leopard needs 867MHz and 512 RAM. I was able to find the ram on OWC but when it comes to the processor i'm culeless. Does anyone have any idea where i can find a processor.
