Optiplex 7050 MT transplant

I'm looking at transplanting the motherboard from the 7050 MT into a new case. I know that I have to get the ATX power adapter. I just need to know about the pin headers for the front panel connections, like the USB, audio (not extremely worried about that), power switch, LEDs, etc.

I saw a company that sells adapters for other models, but not the 7050. Can anyone point me in the right direction?
