Case Open Detect Alarm
If your case has an alarm circuit to detect if the system chassis has been
opened, connect the cable from the alarm into the mainboard case open
detect circuit through the 2-pin connector J3.
J5: Auxiliary USB Connector
This mainboard has two built-in USB ports on the rear edge of the board.
Some system cases have built-in USB ports on the chassis that must be
connected to a USB connector on the mainboard. If you have this kind of
system case, connect the cable from the chassis-mounted USB ports to
the J7 connector.
Panel Connector
The mainboard PANEL connector has a standard set of switch and
indicator connectors that are commonly found on ATX system cases.
Use the illustration below to make the correct connections to the case
