The A3000T is the best Amiga ever!
Ok, it lacks the AGA chipset, but have an internal, native, fully functional scandoubler/flickerfixer.
Plus it have SCSI.
The tower have room to toss anything you want inside.
And it's compatible with almost all cards even made for the A4000.
Did I forget something?
--EDIT--
D'oh! The A3000 (T) never have IDE on board.
