I have a new case for a optiplex 3010 motherboard I can’t seem to figure out where the power switch connectors go also the led connectors and all of them for that matter I have the mother board without the proper knowledge of pins for the front panel connectors. So no power switch for the chassis I am putting it in how can I turn on my pc afterwards if I decide not to use the front panel connectors will I still be able to use this motherboard in the new case? Can I leave the front panels unconnected?
