Photo of the Asus M2N78-LA motherboard,http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c01421635&dlc=en
This photo also shows the orientation (Direction), that the motherboard is sitting in a computer case.
To the very bottom right is the Front Panel header.
The front plastic panel of the computer is the Front Panel.
The area of pins on the motherboard that the cables, (Wires) from the Front Panel connect to, is the Front Panel header. ( F_PANEL )
The Front Panel header, is the black rectangular shaped plastic block, that is sitting vertically on the motherboard.
Has two columns of pins.
4 on the left side, 5 on the right side. Makes it look as though there is a pin missing, at the top left corner.
I'm going to number the pins.
Pins on the Left side starting at the Top, going down;
Pins 1, 3, 5, and 7.
Pins on the Right side starting at the Top, going down,
Pins 2, 4, 6, 8, and 10.
A) Pins 1 and 3 are for the Power On switch. (Power On button)
B) Pins 5 and 7 are for the Power On LED light.
Pin 7 is for the Positive ( + ) wire.
(If the LED light is dim, reverse the wires around)
C) Pins 4 and 6 are for a Reset switch, IF a Reset switch is used. (Reset button)
D) Pins 8 and 10 are for the HarDDrive activity LED light.
Pin 10 is for the Positive wire. ( + )
(If the HDD LED light is dim when operating, switch the wires around)
Pin 2 at the top Right is NOT used. (NC. Not Connected)

I am looking at a motherboard manual in PDF file form, for the Asus M2N78-LA motherboard.
