I had run the lights for the coin slots off of the computers power supply.....and I blew up the PS.  So, I had that other PS laying around at work and I used it for the coin slots.
My wife works for a graphics company.  They do vinyl wraps on race cars, fire trucks, etc.  She designed the side art and made them for me.  It's actually 1 full piece of vinyl the same dimension as the side of the machine.  We just peeled the back off and stuck it on there!
