I would assume that you can buy the case in either format and purchase the
other back panel if and when it is necessary.  I have seen other cases
from several manufacturers that are convertable (I just don't like the
design well enough compared to the really nifty ones we use now) between
ATX and AT by a power supply swap and come with both back panels.

Ok...  Lets take these big server cases, for example.  I've got two of
them here on my bench running WWW, FTP, MAIL services, etc....  They have
power switches on the front panel along with the turbo/reset switch...
The label on the power supply lists the specs for both models and just has
a little dot highlighting which model this one is.  ATX/non ATX, and they
both have power switches wired to them.  So, I figure, you just leave the
motherboard switch on, and use the one on the power supply.

I wish I had a picture online so I could show how they are arranged...

Hmm...  Gotta find me a scanner.  My old Logitech ScanMan Plus doesn't cut
it anymore.  :)
