The small racks for surround zones are really nice. You can load your gear in... bring all the cable in a nice bundle into the rack and wire everything up and then put the whole thing in the cabinet.
I love that pic above with the wheels on the small rack. Thats a great idea! Just have the cabinet built so that you can roll that guy right on in.
