I have an iMac 15" flatpanel. I will at some time get a new G5(6-12mo). I want to buy a hard drive. Right now I need a external hard drive. But I was wondering if I bought a serial ATA internal hardrive - is there a way to connect it to my iMac via firewire until I got my new G5 then I could just install into one of the G5's bays? Sort of getting the best of both worlds.
