as above very common although I must admit that the ones I've had once all warmed up the noise did disappear it's whether your bother and how loud it is
input shaft bearing i would say (in the box), the noise goes when the clutch pedal is down cos the box is dissengaged (where as the clutch thrust bearing is spinning under load when the pedal is down)
