If it contains motors (such as in fans or hard drives/CD etc) they can 
vibrate a little while revving up to operating speed. Some refer to this 
as 'resonance'. This can be caused by slight imbalance of the moving 
part or stickiness in its bearings, or even the motor passing through a 
speed it was not intended to run at while accelerating.

The result should be a mild vibration that disappears when everything is 
fully operational. A similar effect can be experienced when putting a CD 
in a CD-ROM drive as it first centers, then spins up.
