Here is my setup. A little dusty, but a little more organized in the cable department
You can't see the Wii's Hard Drive, it's tucked behind the TV on the right side. That is my only modded system.
From top left to right is my Wii U with 2TB hard drive, Apple TV gen3, my cable box, an OUYA that gets no user, my modded Wii.
Wii Balance Board, PS3, and few games and controllers and accessories are on the second row.
