That is basically an alarm that, when used with a case with the proper hardware, will sound if the case is opened. just like a door alarm for your house.

I believe that the alarm comes thru your audio output. or possibly your case speaker, if installed. I had a Thermaltake case without a case speaker, and I still heard the case intrusion alarm when I opened the case..after a while, I disconnected that feature as it was more trouble than it was worth.

As a rule, motherboards do not come with a speaker. you can get them seperatly for about $5.00. You will not be able to hear the post beeps without a case speaker. That audio is generated before the audio drivers are loaded, so it doesn't get to the audio panel of the MB.

If the case has built in speaker, the sound would emanate from it. If the case hasn't and no external speakers were connected you wouldn't hear anything.

Dell has this intrusion detection on some of their models. It doesn't actually set of an audible alarm, but it throws up a warning during boot that the chasis has been opened. You can go into bios and reset it.
