Jamie,
IMHO 35+ years of electronics including maintaining military electronics
in extreme land sea and air environments....... don't! Civilian electronics
are not designed to handle repeated large changes in temperature over short
timeframes. Additionally as already mentioned by others the change in temp
or 'delta T' is only part of the problem another large factor is the change
in humidity from a warm house/apartment to a cold car which affects the dew
point or the formation of condensation which accelerates oxidization hence
corrosion and can in some cases develop sufficient moisture to cause circuit
shorts. And if the preceeding isn't enough to dissuade you then consider the
increased potential for head stiction (head stuck to platter) in your hard
drive. This can occur in Delta T's of as little as 20 degrees F and can
result in the HD head being ripped off the armature............ resulting in
very degraded performance levels........
