I have a DELL 4600 that I took the 0N2828 motherboard, drives, etc. and put them in a Thermaltake case. The case has a Media LAB and front panel USB and audio ports that connect to the DELL mobo. The connetors are different on the case wiring and do not fit the mobo connectors J9G1, J9C2 (http://tinyurl.com/c4zst).
DELL has been no help with the pinouts. I was on live chat for 50 minutes trying to get the info.
Does anyone know how to determine the pinouts on the connectors, especially the USB (DATA1, DATA2, GND, PWR)?
