The "CASE OPEN" header provides case open-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 case. So, whenever the sensor is triggered by lights or when
you open 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.
