MOTM

When I built my cabinets I asked Paul about
ventilation in the cabinets and he said the air from
the jack holes was all that was needed, I have 5 power
supplys and there has never been any heat at all.  My
studio is airconditioned but I am in Miami Florida and
it is hot as hell year round.  I have left the back of
my cabinets open because I like to look at the
electronics knowing that I built most of the unit.  My
power supplys are mounted on the back of the cabinets,
one blacet power supply 3 motm 900 and one motm 950.

Never had any noise issues at all.
