One of the things that was bugging me about pro/lan was that the back plate for PSU plug and switch was not the right size and looked pretty ghetto. So I found an old 380W Antec Truepower PSU and carefully trimmed the back off of it. It looks much nicer now:
I'm going to get some paint for this piece so it looks nice when I'm done. Not sure if I'll paint it metallic silver or black...
If you notice, it has a molex connector on the back too so you can plug in devices that way. I thought that was kinda cool.
