There is an intrusion switch on the back of my case. The twisted black and white wire has a 2 hole connector on the end. The case instructions say that it should connect to the "Chassis Alarm" on my motherboard. Does that exist on this motherboard? If so, where is it? How is it labeled? If I connect it, will I be able to have the case open while the computer is running? What will happen if I do? Thanks.
