The front panel was kinda ordinary looking so I dressed it up a little. I still had one chrome fan guard left and I was determined to use it. The square hole was sized to fit a case fan and the rest of the frame was covered with screen and roof flashing. Scissors, a drill, tubing cutter, and a pop-rivet tool were all I needed for the entire project. That and beer, naturally.
