Well it's the only Shuttle I've had, and I'm on the point of junking it 
because it is so flaky.  I can't quite bring myself to do it though.

I hate having to know things like this.  That's why I brought a new, 
mostly-pre-assembled box.  I can't see the CPU and/or copper shim, because 
the heat-sink thing is in the way. If I unscrew the heat-sink and remove it, 
will I need to have thermal gel on-hand before I put it back?

Yes, the fan hits full speed when it shuts down, and I think I recall having 
seen the little LED.  But I am really just assuming it is overheating because 
taking the case off and leaving it in an exposed place fixes it.

When I run it with the case on, then slide the case off, I can feel that it is 
really hot in there, just based on the warm air against my hand. Not 
scientific, I know, but there's definitely heat in there.

I'm not really a hardware person, but maybe I'll try it.  I hope Dick Smith 
stocks something suitable. I hope I can uncover the manuals.
