As I said my recommendation it to set it up then test it, change things and
test again.
I have one of those nice Fluke multiple input meters
with several thermocouple wires. It makes it easy to
check things.
On covering the power supply side, I leave about 1/4
of the air slots open towards the front panel.
Randy is right that each installation requires a
little different approach. If the machine is
sparsely populated, one might even add some
blocking to parts of the card cage. Air flow is a real
funny thing. Air flow from a muffin fan is funnier
still.
Do remember, most power supply parts, such as diodes
and transformers are more tolerant to temperature
than your 20 year old memory chips.
