You know, you could make quite a bit of cash doing that - a few people have coloured PS3's in interesting colours, and sold them for a few thousand dollars on Ebay, "the only PS3 in the world that is such and such a colour". Of course, they have a couple of controllers, bigger harddrive, but they sell for a lot.

For example, there was a red one on recently that sold for $6000, I think.
