The “CASE OPEN” header provides chassis intrusion-monitoring function. To make this function work, you have to enable it in
the system BIOS, connect this header to a sensor somewhere on the chassis. So, whenever the sensor is being triggered by
light or opening of the chassis, the system will send out beep sound to inform you. Please be informed that this useful function
only applies to advanced chassis, you may purchase an extra sensor, attach it on your chassis, and make a good use of this
function.
