Step 5: Power Supply
1.Convert it to a Bench Top Power Supply
Computer PSU's provide stable voltage with short circuit and thermal protection. Makes it perfect for a bench top Supply.
See HERE for my very own Instructable on the matter
2.Build A Fireworks Launcher
DONT ATTEMPT THIS IF YOU NOT OVER 18 but if you want to risk blowing your head off be my guest.
3.Recycle it into a fume extractor.
All you have to do is take the guts out of it and hook the fan up to 12v. Great for soldering!
