this same thing was done a while ago
guy foned in to tech tv on screen saverss and told leo all about it
he used a fridge instead
and it only works with mineral oil
the problem is, which the first guy found out
(lol)
is that if yu drop it past -20 or so, the oil co agulates and freezes the mechanical parts of the machine from moving
like platters
LOLLLLL
good temp yields though lol
