Did you happen to notice their award winning power sockets? And the performance cover plates? You won't get full performance without those accessories.

Skinit at http://www.skinit.com/ seems to do this. They will make skins for just about any kind of electronic gadget and you can upload your own image. I haven't used it myself, so I can't vouch for image or build quality.

The radio equipment makes sense. I know in North Korea all radios and TVs are pre-tuned to only receive government broadcasts. If the people had other radio equipment, they could both transmit and receive on whatever frequencies they wished, along with whatever messages they wished. Although, I don't know what stops them from simply dissembling the equipment they already have.

It looks like it is user serviceable:
