Ask and ye shall receive:

The unit is about 2"x2"x2" at present. The 1/8" thick piece right in the middle is the backing plate for the LED/star mount, and the plate at the back is drilled for switch and power supply. A heat sink mounted on one side might be a good idea, but since the entire thing is metal, wouldn't the heat from the plate conduct out to the housing okay? If it doesn't, I can always JB on a heat sink from an old processor or something.

Edit: Oh, I apologize for my crappy drafting skills - the draft I'm most familiar with is beer...
