Case Mod update

[Frito]

Hey guys I finished cutting everything. But I hit a huge snag. The acid I use for glass etching burns and "fades" the lexan It totally sucks balls. So I think I'm gonna have to use paint or something.

So since that's gonna take me a while I just decided to the rest and go back to do the etching later.

Anyway, I'm hooking up the lights. (Fan on order) And I don't have my Multimeter at work. (Forgot it at home) Can anyone tell me which is power and which is ground from this pic?

If I had to guess I'd gamble the one on the right is ground.
