I, too, am transferring the M2N61-AX motherboard from a Dell Inspiron 531s to a Cooler Master case, the 430 Elite. The problem is that the Dell front panel plug connection is a unified/consolidated pl

The part cut from the bold print above is that the Cooler Master has individual plugs that do not cover all of the pins on the motherboard while the Dell plug is unified/consolidated and does.

Better details; I transferred the M2N61-AX motherboard from a Dell Inspiron 531s case to a Cooler Master 430 Elite case. Also installed an Ultra 550W power supply. Power supply tested and works fine. All power connections have been made to the main board, hard drive, etc. The problem appears to be with the front panel connection. There are nine pins on the Dell motherboard. The Dell front panel connector had a consolidated connector plug that covered all of the pins, although it looks as though only six of the connections were being used. Looking left to right, the configuration was such that there were red/yellow wires attached to the part of the plug for the switch, white/black for the HDD L.E.D, and purple/blue for the reset button. The other connections are open, but cover all of the pins when plugged to the motherboard. As for the Cooler Master front panel connections, the connections are not consolidated. There is a plug for the switch with orange/white wires, for reset with blue/white wires, for HDD L.E.D. with red/white wires, and connections called +P L.E.D. with a green wire and -P L.E.D. with a white wire. I have connected the correct plugs to the correct pins, although I am not really certain where the +P and -P plugs should go. Even so, that covers just 8 of the 9 pins on the motherboard with one pin open. One would think that just connecting the power button would suffice just to see if the thing will turn on. Nothing happens. All other components are fine. The pin configuration on the motherboard looks like this ::::. with the last three being the open pins. The Cooler Master manual describes the front panel connections as .:::: with the first pin designated as 'no connection', the next set as GND (ground), followed by LP+, then LP- and ending with USB+5V. I would appreciate any constructive input to see if this is workable, or whether there is something else that may be going on that I am overlooking. Short of solving this issue, my next option appears to be buying a motherboard that is more compatible with the Cooler Master case. Was hoping to hybridize using components on hand, though.
