Clutch release bearing? It does rattle when you are going along but it's so loud it's hard to tell if it's the same.
then i would be seriously looking at the release bearing as that rattle if the idler gear will shut up under load.
the shutting up with the clutch pedal depressed is normally the release bearing but also will shut up the gears as you are removing the drive to them.
you said earlier that it is not the release bearing why are you thinking this

I don't know why I said that to be honest. I always imagined a release bearing to whine like a wheel bearing does. Plus I've had a dodgy release bearing on a car before. This noise isn't like a bearing sound if that makes sense. Its more of a clattering rattling sound. Almost like something in the clutch or gear box is loose and is clipping something as it rotates. I was thinking that perhaps a bit of the clutch was sticking out and tapping the clutch housing or something. perhaps a loose bolt. clutch because it stops when you depress the pedal. Also you can hear the release bearing whine when you depress the clutch but the clattering sound stops??? But as you say depressing the clutch also disengages the gears so it could be something in there? I spoke to my engine builder and he checked all the clearances and says that when he ran the engine it didn't make that noise. So its presumably something that has happened since the engine was loaded up in the car. All a bit of a mystery and as I spent a good amount of hard earned on it I don't see any choice but to take it out and take a look in the clutch housing for starters.
the release can make a similar noise. but it is as i said before more like the idler.
next thing to do is raise the revs a bit and see if it smother out the revs and shuts up the rattle. and get someone to hands on look.

My straight cut box makes exactly the same whirring noise until you disengage the clutch.
The rattle sounds like idler gear to me though.

It could if the crank thrusts are worn?
