I have an eMac running on 10.2 right now. 800MHz G4. I'm going to upgrade it to 10.4 Tiger. Question.... it only has a CD drive. No DVD. Apple has discontinued the media exchange so that's not an option any longer. My only other alternative is to get an external DVD drive and do it that way. They said it would hook into my firewire. They assured me that this eMac does have firewire. I don't usually fiddle with any hardware on my computers. How much do these external DVD units cost? And how do I hook it into the firewire?? Total newbie with hardware! I can take it into the apple store and they will charge me 30.00- 50.00 to install it. Is it worth taking it in? Thanks for any help.
