	At least that would make it easy to test for by taking
the computer out of the confined space and letting it stand 
unencumbered.  Of course if it still has the problem you still
have the problem.  If it fixes the problem but it would be better
in the desk then you need in case of metal desk hole punches
or chassis punches like we used to use to put tube socket holes
in the chassis of radios and other equipment.  If the desk is
wood you need a rotary hole saw and maybe an extension so you
can put holes at the back of the cabinet.  Maybe more holes
and put screen over the holes so that hair cannot get into the
computer's own intakes.
