The “CASE OPEN” header provides chassis intrusion-monitoring function. To make this function works, you have to enable it in the
system BIOS, connect this header to a sensor somewhere on the chassis. So, whenever the sensor is triggered by lights or by the
opening of the chassis, the system will beep 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.
