7500 is not so involving. You can either modify the back plate a bit 
(not the actual cube enclosure!) or run it without the plate at all 
which will improve the cooling. 8500 and 9000 both require you to move 
your DC board, and that is something I wouldn't do. They also run 
hotter.

7500 is faster than the Radeon that I currently use. 8500 is the 
fastest one, and 9000 is a tiny bit slower than 8500.

All three of them can do it. I'd suggest you go with 7500, at least 
that's what I'm going to do.
