I am wanting to install Leopard. Everywhere I check for minimum requirements it says the PowerPC is required. Since I'm shopping on ebay, and items not returnable, I want to make sure before I buy. When I check the 'About this Mac' this is what it says Machine Model: Power Mac G5 CPU Type: PowerPC 970 (2.2) Number Of CPUs: 1 CPU Speed: 1.8 GHz L2 Cache (per CPU): 512 KB Memory: 512 MB Bus Speed: 900 MHz Boot ROM Version: 5.1.5f2 Serial Number: RM410Z67NVR Based on this, I am thinking there should be no problem installing Leopard. Am I correct? Sorry if this is a stupid question but I wasn't sure if by Power PC they meant model or what I have.
