Since i have to hide a VGA cable (with connectors), S-video, AC power cable (with connectors) and speaker wire, I need something special for that corner, the standard molding won't do it. A flat strip of white wood would do it (3 inches wide).
There is also a PC behind that box near the cables. and I plan on painting the sensorbar wire the same color as the wall to make the wife happier. I didn't plan on spending that much time and effort on it, but she wanted it to be as stealth as possible. I had all the equipment except for the rear-speakers in storage, so it didn't cost too much. The transcoder, adapters, and cabling did cost about $200, but now that room actually gets some use and I can play Wii while the wife watches TV.
