I need to replace an internal hard drive in my Power Mac G4. Here are the specifics: Machine Model: Power Mac G4 CPU Type: PowerPC G4 (3.3) Number Of CPUs: 1 CPU Speed: 1 GHz L2 Cache (per CPU): 256 KB L3 Cache (per CPU): 1 MB Memory: 768 MB Bus Speed: 133 MHz Boot ROM Version: 4.5.7f1 I basically have tree questions: 1) What internal hard drive would you recommend? (Brand, model, etc) 2) How difficult is it to remove and install an hard drive on this model? Is it as easy installing RAM/SIMMS ? 3) What should I be aware of or watch out for if I install a new hard drive myself? Any input would be welcome??
