The wall wart you see to the right is a 12v supply wired to two led fog lights I found at the auto parts store. They are each a single row of 12 leds, and attach to the right side of the rack with the included 3M double sided tape. I didn't take the time to wire a switch, so the 12v supply lead is just long enough to for the wart to lay in the bottom of the rack when I unplug it.
The leads you see disappearing upwards are firewire for the macbook pro and a firewire and power cable (the other wall wart) for my lacie rugged hard drive.
The HD24xr's analog outputs are snaked to a mixer when live to two is required, and the Pro VLA and Rev7 are patched as needed.
The two tubefires' mic inputs are extended to the front of the rack with a 16 XLR patch panel, and overflow is handled with the profire's mic inputs on the rear to achieve a total of 24 channels to DAW and HD24 simultaneously.
