I have the Middle Atlantic rack shelf as well. It was simple to install, works well and gives it a nice, finished look.
They make custom rack shelves for about 5,000 different components. I also have one for my Denon 2910.
I have the 29U Slim 5 rack with the following components:
Zektor 5x1 DVI Switcher
Denon 2910
Outlaw 950
7 Outlaw 200's
4U drawer (good for xbox controllers, etc.)
Panamax 5100
Several 1U spacers
The slim 5 rack is pretty nice. I have the oak side panels for it too. They help with wife acceptance factor.
Good luck,
