Hate to rain on the wood parade, but aside from the heat insulation  
issue, wood also has the tendency to
build up and store static electricity (I don't think I need to explain  
why that's a bad thing). Also, considering
the time it would take to manufacture a single case it would add  
considerable cost to the finished product over
the cheap aluminum cases that are pre-made for the board.

While I agree that it would look WAY better than a cheap aluminum box,  
I don't think it's practical.
