I just bought a G4 and would like to upgrade some things. First off, I would like to upgrade the CDRW. Will any IDE CDRW work or do I need an Apple specific CDRW?? Where would I find an Apple specific CDRW?? Second, I would like to add an internal Zip 250. Again will any IDE Zip drive work?? Where could I find the bezel for a Zip drive?? Third, I want to add a DVD-ROM. Will it work with the installed ATI Radeon 8500, or will I need a decoder card?? And finally, I'd like to add a sound card. Will a SB Audigy work?? Or do I need an Apple specific sound card?? All help and info greatly appreciated. I've been building PC's for years, and thought it was time for a change.
