I'm not a big fan of putting the A1200 in a tower. In my opinion, the only good reason would be if you wanted to use PCI-cards. And some turbo boards need extra cooling, which is easier with a towerized A1200.
Otoh, a classic A1200 can also be heavily expanded. Most turboboards (I use a Blizzard 1260 with SCSI-card) work like a charm in a standard A1200. Likewise with the Indivision AGA, while I also replaced the standard psu with a heavy duty one. And I use a 4-drive SCSI-tower for my external drives.
All in all, I have a heavily expanded A1200, but find no need for towerizing it.
