That's a nice quick way to get a dead hard drive ;)

Hmm, yes, kind of key symptom that ;) 

My take on the convection debate: no, NEVER leave the case off your
computer. Firstly, convection just isn't efficient enough to cool your
chips, and you're taking about five years off their useful life. Ditto
hard drives.

Secondly, your PC shouldn't be a dust trap. Leaving the case off just
means it gets mucky. There is such as thing as conductive dust as well,
although that's kind of rare. More dangerous is the housewife with
'magic-o-dusto' who goes around giving everything a quick dust: dusters
attract dust, usually via some sort of static / differential charge
thingy. Not good.

Cheers,

Alex.
