I am in the process of buying a hard drive for a PowerMac G4 that i just purchased. The computer doesn't have a DVD drive, just a CD. I have a copy of Tiger that could be installed but I would need a DVD drive. Would I be better off buying a cheap copy of Panther online somewhere and just using that, or buying a DVD drive and installing Tiger? Or finding another way to install one or the other on my Mac? Any suggestions?
