In my shop I use 30 watt LED fog lamps I found online for spotlights at my equipment.  Only issue is they are 12 volts.  Enter having a 12 volt computer power supply and adding power outlets to it.  Now you can run 4 lights at 12 volts.  This makes #3 so far.  Recently moved my drill press across shop and had no power supply outlet on that particular side.  Decided now was a good time to upgrade the old one.  It ran a roll up shade I use a old power window motor to roll up and down as well as a mixer out of another power window motor.  Other than that it sat idle.  Still runs everything just added the 4 outlets and made a new box to accommodate the inner workings better.  Used some aluminum from our old shop doors at work and cut with a multitool.  Drilled as needed and recessed the outlet side into the box.  

 

Thanks @Larry Buskirk for his computer box post.  Inspired me to make this much better looking as well as some ideas for how to lay it out.

 

 

Enjoy and be inspired.

Did you create an "air exhaust port for the power supply?

Yes, it matches the port exactly but is not seen in pictures.  It is on the back with about 2 1/2 inches of space between box and wall.  Previous it was on it's side and vented toward the front.  A lot of dust was in box so I tried this direction instead.
