In my COD MW2 worklog I mentioned wanting to make a Chassis to Door power connector so I did not have to unplug led and fan wires every time I opened the case. Here is my concept. If you have another idea on how to achieve this please post it.
The connector with the long side would attach to the door and the other to the inside of the case. There would be two 12v pins and 1 ground. The pins could be made from anything conductive and could even be a screw.
