gasp! You mean, you don't?? What's the point of going then, if not
for a ride in the tiny red car with 42 other clowns???

And that's exactly what it did. And yes, more flow would have
cooled them to a point where the material wouldn't matter, but my point
was to see if under the right circumstances an aluminum case would cool
better. And yes it is probably a moot point because anyone that has an
aluminum case is not likely to have a lack of fans or airflow, but the
fact remains that the aluminum case *can* make a difference if the
circumstances are correct. A difference worth the price difference,
probably not.

Just don't be the first to get into the tiny red car!
It can be hard to get out of. ;-)

The circumstance would have to be very extreme- the system
would not operate properly long-term like that, so I
completely discount this situation as the aluminum didn't
actually help, the system was still too hot.

The fact remains that for any reasonable computer system
implementation, aluminum is not going to help enough to be
considered relevant. We don't have to acknowledge a
situation where there is an extreme problem, as then we'd
have to consider things like "having a sprinkler system in a
case is a good idea" to cover situations where we're growing
flowers in there or putting out fires.

FWIW, most of the time I'd rather a steel case, because for
the same thickness steel is sturdier. Some of the high
priced thicker Al are nice, but come to think of it I might
just as soon have it be that thick a gauge of steel instead
of it were possible (seems nobody makes a PC case anymore
over 1.0 thick, sometimes 1.2 on rackmounts but not so
common anymore).

Of course it helped. It had to if one box was cooler than the other and
it ran in both cases for over 8 hours each time.

Why? It shouldn't have to do anything but hold stuff and not fall
when you lean on it.

Helped like putting a bandage on a cadaver?

No, it did not help because it did not result in an
acceptible operating temp. if it doesn't meet this basic
goal, it was a misguided focal point, a detrimental thing to
consider at all... so not only did it not help, it hurt.

Thicker metal flexes less, meaning less strain on boards,
and thin walled component cases (like optical drives).

It can matter merely scooting a case across a desk, or
picking it up, let alone transporting it. That's no
guarantee it will break a system immediately, but given same
design of case the thicker metal has an obvious benefit.

Thicker metal also vibrates less, and the mere weight of
components can actually deform a cheap case a little.
"Little" may not be but a millimeter, but we'd talking about
parts that mount to the rear and have slot contacts, so a
millimeter can be a lot.

Better question is, why would you NOT want a sturdy case?
Would you want a refrigerator or automobile that is flimsy
too? So what if it weighs 10 lbs more, are you lugging it
to lan parties every weekend?

Same situation with any quality merchandise, thin and flimsy
is just poor quality goods if the weight reduction isn't
targeted towards an important function of the device.

Why the long discussion about the temperature advantages of metal
cases? The *main* advantage of metal cases is RFI/EMI suppression,
and to a lesser degree, rigidity.

Trying to get a plastic case to pass FCC testing can be frustrating,
indeed.

Agreed.

.... requires metal paint that costs as much as metal
sheeting would.
