have to admit, the G5 is probably the first Mac tower I actually like. It should definately have more drive bays, though. That's the whole reason PC's are more cluttered, after all. Nobody would buy a PC tower without extra drive bays.
I'm still not sure about the case, apple seems to be going all metalic at the moment (it was plastic/glass before).
At first I thought the same about the drive bays, but thinking about it why would you need them? The superdrive does everything you'll pretty much ever need. Still I suppose if you are paying that much, you'd want the option of more expandability.
