I did some research. I did not find any diagram in your case manual, but I did find this:
Connecting the Ports and LEDs
Note: Please refer to your motherboard manual for specific pin outs or location of
front panel connectors.
1. Connect the Reset switch (labeled RESET SW) to the motherboard at the RST
connector. Polarity (positive and negative) does not matter for switches.
2. Power Switch (labeled POWER SW) connects to the PWR connector on the
motherboard.
3. There is no Power LED in this case. Three illuminated case fans will turn on
when there is power to the computer.
4. Hard Drive LED (labeled H.D.D. LED) connects to the IDE connector. For
LEDs, colored wires are positive (+). White or black wires are negative (–
. If
the LED does not light up when the system is powered on, try reversing the
connection. For more info on connecting LEDs to your motherboard, see your
motherboard manual.
Then, I pulled up your motherboard instructions and found:
Connect the power switch, reset switch and system status indicator on the
chassis to this header according to the pin assignments below. Note the
positive and negative pins before connecting the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may configure
the way to turn off your system using the power switch.
RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset
switch to restart the computer if the computer freezes and fails to perform a
normal restart.
PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the system
is in S1/S3 sleep state. The LED is off when the system is in S4 sleep
state or powered off (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED
is on when the hard drive is reading or writing data.
The front panel design may differ by chassis. A front panel module mainly
consists of power switch, reset switch, power LED, hard drive activity LED,
speaker and etc. When connecting your chassis front panel module to this
header, make sure the wire assignments and the pin assign-ments are
matched correctly.
Below you can see where this stuff attaches to:
Good Luck!
