i found a couple of pictures of the board on ebay(no help) dell was unwilling to provide me with link(usual). on the board it's self, where the front panel connectors attatch, does it have any lettering next to the pins? for example pwr, +hdd-, rst,..if you have a after market case the wires should be labled in much the same way, the power and reset leads make no difference + or -, but the power led, and hard drive led must be correctly + or -, it doesnt hurt if they get crossed, they just wont work, this being a dell board it may or may not have a reset on the board(should) but dont mean it will. if the board has no lettering, look at the plug from the orriginal case, follow the wires to what they went to, power switch, power led,....ect. write down the colors and what they attatch to, then match the plug to the board and make a map of the pins.
