These are some *great* ideas... and thanks for the insight, BJ.. I notice you mention mounting on the back. The basis for my question is... speed controls are notorious for generating heat... which kills electronics unless dissipated... so one designed for "perimeter mounting" would need to be designed to dissipate its heat through the front and back while those with apparent heat sinks seem to have them around the perimeter, where air would not flow if panel-mounted.
It sounds like the best alternatives so far would be either to follow BJ's suggestion and/or start buying and disassembling the SC's to ensure their heat sinks are able to do their job. If one had its heat sink inside the box, removing the box and replacing it with my own vented box (since it'll be out of reach for fingers) might be an option too.
BJ.. Is it the heavy-duty one that has the slot holes, that you are aware of?
I guess I could also likely remove the speed control pot from the case and mount it through the face, with the rest of the electronics still in the box and inside the cabinet. Any flaw in my logic, assuming the pot isn't soldered into a printed circuit board?
