N.J: I only said it should go because the enclosure contains higher power, higher voltage circuits, In my mind what I see there would be like having a fuse or breaker box with a wooden back for example. The potential for a hot connection or a spark to start a fire is present.. If this enclosure had nothing but L.V low power / datacomm stuff and a receptacle mounted in a proper box to plug in power supplies, I would think that kind of set up would be acceptable to having a wooden backboard, such as what those Hoffman enclosures are sold for I would imagine.
Just my opinion tho..
