Hi, I'm finally upgrading out of the G4 era and buying a used G5 tower. However, it doesn't come with any install DVDs. So I really want to find a 10.5 install DVD, because I'd like to finally upgrade from 10.4, but I can't find any stores that sell 10.5 anymore. Does anyone know where to find a new 10.5 DVD for sale? (I'd prefer to not buy a used scratched up disc.) I did see one place (Amazon marketplace) but they wanted $170 for the install DVD, and that is more than I just paid for the dual G5 tower which seems pretty crazy. Please let me know if you know of a store still selling new 10.5 install DVDs for a reasonable price. Thanks!
