    I was workin in the ofifce and one of the macs that wasn't being used all of a sudden started making a loud noise. No activity on the comp whatsoever. the case was vibrating thats how loud the noise was.

    I shut it down quickly opened it to see if any cables some how came into contact with a fan. I moved some cables around and nothing. Still happens. LOUD AS HECK.

    I don't have MDD g4 its a later one than that.

    Any ideas?

    An off-balance CD in the drive?

    Some of those tend to rattle the computer when they're on a hard surface, and they can spin up at odd times, plus they can be quite loud.

    can you leave it open and turn it on?
    that way you'd know exactly where it was coming from... could be a fan bearing going off like mine did a while back.

    I bet it is the hard drive.
    Disconnect power to the hard drive and boot from a FW drive or CD.
