I have an Ibook with a 500 g3, 128 ram 15 gig hd and a 24x cd rom. i was wondering if it was possible to purchase a new internal cd drive with dvd and cd-rw capabilities, or just cd-rw capability. if so how would i go about doing so, or am i limited to buying an external cd burner? but it would be much preferd if i could get an internal, with school and stuff. any sugestions?
