I prefer the A1200 with a solid state hard disk or compact flash card for a hard disk. Mine sits on the corner of my desk and runs the BBS 24/7. It has been on for over a year non stop, makes absolutely no noise and produces very little heat.
I do miss the 3000T I used to own but when I think about it, it was slower, had less ram, no AGA, was noisy and even with 3 hard disks it had less than half the storage of my current A1200.
