Re: On cooling...
There was an IBM frame that used liquid nitrogen to cool the CPU.
BTW adding fans won't help. The issue is to move the hot air away from the CPU, not blow cold air on it (although if you could arrange that, it would be nice). Running with the cover off is the surest way to overheat the CPU, because there is no orderly flow of air over the components. The IBM PS/2 servers would not operate with the cover off.

I use airflow dynamics...
and "Path" my heat out of machines... so intake never crosses exhaust... usually Front=>Back
But this time, I used a Venturi effect with the Big Fans... and push the hot air into the Stream.
Works real nice, the Drives I am using used to be in IBM Storage Drawers... they ran ~95 degrees F with refrigerated cooling... right now ~105 degrees F. Very little noise too... those big fans are nice for that.

"Airflow dynamics?"
Is that anything like "Never put an IDE drive between two SCSI drives so that big fat SCSI cable covers the entire thing, insulating it and causing it to bake thoroughly?
I *still* bear the scars from that.

I can't help it
it's the only time I've ever reached in to a pc and seriously BURNED MY HAND.
Like I said, it scarred me. I was depressed for almost a year after that.

Add a component and it does work
Running with the cover off is the surest way to overheat the CPU, because there is no orderly flow of air over the components. My system at home (2 more weeks till I break down and buy a new one) is running with the cover off (dead power supply fan). I have a mini fan blowing into the box that cools it just fine. Why should we ask our military to die for cheap oil when the rest of us aren't even being asked to get better mileage?

Ugh :)
Any gravity mounted drives? :)

Huh?
You mean like the one I've got hanging and swinging in the breeze from the IDE and power cables?

LMAO!
Damn, I can't begin to count the number of times I've had to do that...
Any deity worthy of a graven image can cobble up a working universe complete with fake fossils in under a week - hey, if you're not omnipotent, there's no real point in being a god. But to start with a big ball of elementary particles and end up with the duckbill platypus without constant twiddling requires a degree of subtlety and the ability to Think Things Through: exactly the qualities I'm looking for when I'm shopping for a Supreme Being.

Re: Huh?
Might as well hang some wind chimes from the case inner top. Maybe also one of those nice prismatic glass things to catch the sunlight, like hippie chicks used to like - wake'n bake and nice colors.
