My Father in-law smokes the odd cigar and so he had a few old boxes lying around and I grabbed a few of them. One is being used as a box to put all my old ram.
The other one I had an idea what I could use it for.

This was what I started with, I forgot to take a real "before" shot but you get the idea. Its a crappy little 80w ATX PSU that i want to use to power lights and LED's with.
After a day in the shed I ended up with this.
I used a 40mm fan from an old fried nvidia card, an unused switch from a Cold cathode, a piece of speaker grill and a few left over leds from another project.
Of course eventually the lid will be glued shut (there are some little hands around here) and i just need a 40mm fan grill for it but I think it turned out rather well.
