Is true metal cases have an impact on temps.
The bad part is how much is unknown.
I've never seen anyone PROVE an Aluminum cas is any better than a steel one...

More important than this is another issue that get's CONFUSED with the one above.
IMHO the main reason people have problems cooling clear cases is that the cooling is very poorly planned out. Most of them are smaller than normal, cramping high end components that get stuck in them, while not offering the amount of cooling required for those components in the first place.

Pick the right case and come up with the right cooling and you'll do A-OK. I built and sold a
[email protected] Tbird on an nForce motherboard with a GF3 ti200 past 500 speeds last year in a clear case...
It had no problems at all... The point is get a case with a good layout and make sure you give it adequate cooling.
The clear cases run hotter is a complete myth IMO... If they'd design the damned things better, the stigma would have never surfaced.
