I was actually talking about using the phenolic as a mounting surface. It does come in a lot of colors and I would imagine that it could be artistically incorporated into a chassis design.I have seen a light bulb that sat within inches of a piece of plywood and it did char halfway through the plywood, although it never did burst into flames.
I would think it would be okay to use an all wood chassis, I don't think there is enough heat to cause it to combust.
