Got an HP Compaq dc7600 tower for cheap locally. Works fine, just wanted an ATX case for a potential sleeper build project. Cleaned it thoroughly inside and out. The outside metal cover comes off completely from the shell which makes it pretty easy to spraypaint the machine. I still have some work to do on the front panel but happy with how it came out overall. Also I had to use isopropyl alcohol on the LEDs cause I forgot to tape oeuvre them.
