All, I have a G4 PowerMac DP 533 and have been told by the Apple Genius at our local store and Apple Care as well that I can only use a 120 GB hard drive max for an internal drive. As I can get a 180 GB drive for the same price I'd rather use that one. Has anyone been able to use an internal HD bigger then 120 GB by using a PCI IDE controller? I was told by someone else that by using that it would allow me to install and use the bigger drive. Thank you. Glenn
