I think "Anything Amiga" in Australia had towers,
may want to check with them. You could also
build a better one yourself, costs less money
but requires a little skill/patience. The most
difficult part would probably be creating the
backplate, but with some good measurements and
a template you should be set. Plus there are
some full-size server towers out there that
look much better than Elbox towers.

The best one IMO was the RBM tower...too bad
they're nowhere to be found.
