    Intru = Intrusion Alarm.
    Some cases (usually servers) have an alarm that goes off if the case is open.

    More specifically:
    Those header pins go to the chassis intrusion switch found on some cases.
    You turn the feature on/off in the BIOS.
    I wouldn't use it even if my case had a switch.

    Here is your manual:

    Fell asleep anwering that din' I. Missed a bunch of it.

    This is a front panel connector.
    If you don't front panel things to connect to them then you don't need them.

    Pins 2 + 4 = Yes, The power LED.

    Pins 15 + 17 = SMBus - System Management Bus.

    Pins 9 + 11 = NIMI, Network Information and Management Infrastructure
    Is basically a Linux Network Monitor.

    Pin 13 is +5vsb . I don't know why that would be there unless NIMI uses it.
