As long as the condensation was kept out of the computer, I cannot see why it could not be used.

However, a far easier solution would be to figure out why the computer is getting so hot and address that. Turn the fans up, warranty it for bad paste, etc.
 
The condensation off the dry ice container would be the enemy. Not the dry ice itself......

yes, that is what i was thinking. Dry Ice is no effin joke. it takes only 5 seconds of exposure to bare skin to burn. I had a guy at work handle it with bare hands for like 20 seconds and he had blisters on his hands bad. Went to the emergency room.

I wouldnt put dry ice anywhere near my computer. Here is a link to some info.

I would just get an Mstand and put a small fan of the bottom of the computer. Maybe if you had extra money you could get a dell mini and try an experiment to see what happens with that, but i wouldnt potentially put my $2500 computer in harms way on purpose. It is already on a suicide mission with 2 cats running around me constantly!
