Building Your Own Air Chiller
Several people have taken the time from their busy day to submit the how-to make an air chiller story that's currently running on OCMod.com. Me, I think that if I open my case the magic pixie dust that runs my computer will fly out, and my bad hardware karma will ruin my machine, but hey, maybe you'll have better luck then I.
You'll need to use this to cool down VA's hot stock prices!!
Hey Jack, You don't know Jack:)
Actually...leaving the cover off of some designs will cause your CPU to get HOTTER. This is due to exhaust fan placement. This is mostly true of newer systems which use strategically placed fans to create a path which air will flow across the cpu. By removing the cover air now flows in the side, through the exhaust fan, and the airflow around the CPU is not in the air flow path.
So, yes, the cover keeps liquids off of your CPU, but the cover can also be there as an effective cooling solution.
Since I just did that long thing on CPU cooling, this reminds me directly of VW air cooled engines. People were constantly thinking they could remove the engine lid on VW's with air cooled engines, it looked like removing the lid would naturally increase air flow. VW's are designed with the hoods to be closed however, so removing the lid completely can cause overheating:(

No self-respecting geek would run a piece of computer equipment with all the cover components installed!
IMHO, a heat exchanger and some non-conducting fluid is probably the "best" solution. (There was an article a while back on cooling via oil and an air conditioning unit, but the link was very dead, the last time I checked.)
Alternatively, find a material that semiconducts at extremely =HIGH= temperatures, and stick your computer into a vaccuum flask.

What they *should* teach in school is that "than" and "then" are not homophones. If you pronounce them properly they do not sound the same.
I see even classic Slashdot is now pretty much unusable on dial up anymore.
Sounds like you're talking about room air conditioners in your real world example. I learned the hard way that the condensation actually takes place in the "indoor" half (where the air gets chilled)and has to be properly channeled, through gravity and/or suction created by the "outdoor" half of the fan, through the separating wall to the "outdoor" half (where the heat removed from the chilled inside air is released into the great out of doors, which, I suspect, is why summers seem hotter than they did years ago-more air conditioned spaces=more heat pumped into the outdoors).

Ever notice how those same computer gods like to wait until you blow all your current disposable income on a new part for your computer before they break one of the old ones?

For the most part they do suck.
There are always exceptions though. The public school that I attended was very good. The students were competitive about grades (it was cool to get good grades). Hell, there was even a group of Japanese who visited to see how we were getting such good results.
I learned BASIC in 7th grade (12-13 years old)and assembly language in 10th grade :) That may not seem like a big deal to some of you uber-nerds, but consider what 10th graders are learning in their "Computer Classes" at most schools these days. Microsoft Office, maybe? Corel Draw? How to use a search engine to find the best warez? :P
There is no excuse for ignorance though. If you want to learn you can find a way, especially in the USA. There are public libraries all over the place (in which I used to spend a considerable amount of time, I might add :).
I run a 900 mhz Athlon Thunderbird. There are 8 fans in the case trying to keep that machine cool, and with a Thermaltake Super Orb and Arctic Silver, the processor is still running at 125 degrees regularly. I'd never settle for the factory heatsink and processor goop with temperatures like that.
Yes, 900 mhz is the factory setting. When you have a card in every slot of your machine, it makes it harder to cool.
But what about things that can get suspended in it? That's where the trouble comes in.

Overclocking is just fun, for the sake of doing it. Not overclocking is like buying a sports car and leaving it stock.

Condensation? I still think that would be a major problem in something like this. You'd get water in the case. But that's just my opinion. I could be wrong.

OK, well points 1 and 3 are well taken, but in a closed system point 2 is kinda moot - that is, there won't be a problem if the system is completely closed, as there won't be any open flame, and if the oil gets beyond its smoking point, you have bigger problems with the system.
Still, points 1 and 3 kill the idea completely anyhow (though I wonder how fast a solvent it is - if it is a good solvent, why did people immerse thier motherboards in it - ignorance?). So, the idea would be to get a fluid with as high a specific heat as water, non-flammable, non-conductive, and doesn't act as a solvent. Fluorocarbons are an answer, but most aren't very environmentally friendly, and none are very cheap. I am thinking something like Fluronert might work - but all of that gets into a realm of of chemical workings that I don't understand.
Distilled/de-ionized water could be used instead - less conductive, anyhow...

Case Fans
Why do people always go with the 12 volt fans? There exist same size (as well as larger) "muffin"-style fans that run on 110-115VAC, many pump 100-200 cfm (I had one that came from a DEC mini computer powersupply - had to mount it on a board to keep it from blowing away when I was playing with it). Sure, they would be extremely loud, but think of it - you can easily get that computer center droning noise you know you've always secretly wanted...
Coolant
Instead of water, why not pump mineral oil through the system? People have immersed thier systems in circulated mineral oil, but that is messy. Use a gas tank pump to circulate the oil (the pumps are designed to resist the solvent power of harsh chemicals, like gasoline). You might not get better cooling than water (don't know whether you would or not), but you wouldn't have to worry about leaks shorting your machine out, since the mineral oil isn't conductive (else why would people immerse thier machines in it).

Years ago, I had a power supply like that. If it was firmly fastened to the back of the case with all four screws, it'd glitch and cause the computer to reboot. Leaving it somewhat loose appeared to alleviate the problem somewhat. IIRC, I eventually "fixed" the problem by removing the upper half of the power supply case. I don't know if it was overheating or if there was an intermittent connection on the power supply circuit board, but it didn't give me any more problems once it was opened up. (It may not have been the safest setup, but I know the danger involved and nobody else pokes around inside my computers.)

Too big to fail? Does that make me to small to succeed?
Three reasons:
Mineral oil has a much lower specific heat than water. You need to circulate a lot more of it to get a given degree of cooling.
Mineral oil is flammable.
Mineral oil is a very good solvent. Goodbye to any plastic parts. (And to your rug if you spill any. And imagine the effect on the building.)
The Cray II was cooled with a clear liquid - a fluorocarbon, I think. They also had a debubbling gadget in the room near the computer. Looked like an enclosed fountain made of plexiglass. Very artsy. The two Cray IIs I saw had very distinct fountains, which made me wonder if they were distinct artworks - at least at first.

Gee, a homemade air cooling device is pretty cool, but if you're going to do it yourself, why not spend your time making the most kick-ass cooling system you can? There are several places that sell kits, and lots of good information. If you're going to make your own cooler, at least do it in style!

No, youll just make it run at the speed its supposed to be running at.
I lived in Farmington, NM for a few years, in one of the richer parts of town. Almost everyone uses them there.
Granted, ours was different in appearance and operation than what you've linked to here, but the idea is the same: use water in the air to cool stuff down. As Farmington (and all of New Mexico, really) is very dry, they work extremely well.
It's evaporative cooling at it's finest.

Funny, when loading C64 games we had to sit absolutely tight and not talk at all, lest the cassette-trolls would pay a visit and load errors either screwing the load completely or making the graphics more blurry.
Pixies, trolls, gnomes and elves commonly visit and plague low-tech equipment. You gotta know how to appease them, especially when programming. I only wish someone could devise a cool religion for this, so that our problems might go away.

When the winter weather got down around -30C, it probably would have been worthwhile to build a ledge outside someone's window, and put the microcode machine there, but nobody realy thought about it then.
(un)fortunately, I now live in Vancouver where it rarely goes below freezing. This means that I can't use the weather to help overclock my machine. Such is life.

I ran a real cold garden hose over my brother's head when we were young and he got a huge headache out of the deal. Maybe there is more to it.
Sounds more like a grounding problem to me.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
Personally, I believe that the computer gods smite you if you put the cover on after installing hardware before you even test it.
If you want to be really sure that new card will work, you'll not screw it in completely until you know it is fully functional.
They will punish you for your audacity, and you will find that you *accidentally* knocked out your IDE cable when you were mucking around in there. You will not know until you get the non-system disk message.
Be fooled not. It was the computer gods, and they are laughing.
Yah, theres a nerve on the roof of your mouth which causes icecream headaches.
if you ever get one, try rubbing your tongue on the roof of your mouth to try warming it up, it might help.
Mommy, I won't go to hell for just overclocking once will I? I sweat I won't do it again!
Sure this is off-topic but I have to support Hemos' assertion that PCs run off fairy-dust. Where does fairy-dust come from? Why, Asia of course! After all, my local computer retailers are all Asian and have no problem getting any hideous combination of hardware functional. Me? I try to replace a hard drive and smoke starts billowing from my GeForce.
Now I'm a reasonably intelligent man, yet it seems every foray into my PC case ends up in boot errors, bloody knuckles, and the invention of new and creative swear words. You may contend that most PCs are incapable of engaging in sexual relations with their mother, but you wouldn't know it to hear me yelling.
I'm a decent web developer, I can code in PERL, I've administered Linux and MySQL. I know the difference between baud and bps and have dabbled in Assembler. But am I the only geek who can't open his case without dropping a screw into the power supply? Help!
PS - Does this mean Thomas Pabst is actually Asian? He's all a-glitter in pixie dust...

No, that was one grammar mistake- "then" should have been "than". the "I" is correct, regardless of how much more natural it feels to say "me". The trick to remember is the implied verb. Here's what I mean:
..."more than (you'd like to have hot steamy sex with) me".
Maybe you'll have better luck than I (had)
see - that's correct. If you use "me", you change what the implied verb is:
Maybe you'll have better luck than (you'll have) me.
Not only is this not what he intended to say, it also doesn't make any sense. This is a common mistake. Just remember, when you say something like "There's no way you want to have hot steamy sex with Natalie Portman more than me", you're actually saying

Funny, my comp at home doesn't work with the case on! I swear! I think it has to do with the CD-ROM player, since I also removed the screws from it.
When I put the screws back in my CD-ROM and/or put the case back on, I get all kinds of trouble, but without them everythings fine. I suspect something to do with heat...

Some users overclock their computers so that they can run SETI@home or other distributed clients faster. This irresponsible behavior can not only damage that user's computer, but can provide flawed data that could possible ruin the entire distributed project. Please, I urge you, don't follow the herd, don't overclock your computer. If performance is that important to you, go with the reliable solution and buy a faster machine.

Actually Swamp coolers are not reserved for *poor* people. Growing up in the southwest we had a swampcooler because of it's inherent effectiveness in arid climates. For those /.'ers that aren't familiar, a swamp cooler works through a process of evaporation, however once the relative humidity reaches a certain point the swamp cooler fails to be efficient. My point is that swamp coolers are not a "ghetto cooling solution" but rather an inexpensive and effective method to cool things. If saving money designates somone as whitetrash....then hell...I guess I have no teeth and watch WWF.

Those disasters happened entirely independant of each other, and I know power isn't an issue as I have had the power supply looked at and I've had the machine plugged into different locations when parts went bad.
Moding my case with something like that would cause my bad karma to manifest itself physically into Murphy himself to smite down my poor machine!

Yeah, the small chapel at MIT is surrounded by a moat with vents that blows air into the chapel cooled via this method. From what little information I have seen on the net about this school, I gather they are far from poor white trash. Too bad they didn't let me go to their school or I could have demonstrated this effect.
True, true.

Now the guy who did this little thing has *got* to be white trash (I speak as one of the chosen myself) When I was growing up this thing was called a swamp cooler and was used to cool cars and homes in the deep south.

Something I always wanted to do, living in northeastern Quebec, and it being somewhat cold up here most of the year, was hook up some air hose to my window from my computer case, and an air filter w/fan, and cool down my CPU in that manner. No fancy peltier pumps or uber-huge heatsinks with 1000cfpm fans, just really, really cold air from outside, for maybe $10 in hose and a small fan. Saves on power, too. Now if there were a good, cheap way to catch some of that cold air for the summer (when it is really hot, oddly enough), I'd be set.
