I have not looked into this, beyond what you have already said, but there are already PC air conditioners available. I'm not sure how good that they are, but they aren't terribly expensive.

EDIT: The thing to consider is condensation. If it were much colder than ambient temperature, condensation would form, and possibly ice, neither of which would do a PC any good.

I had to go back and check this out. Normally, you would be correct. However, you do not use condensed air, you use a dry gas, such as Propane.
The reason for this is that you are taking water out, there should be none in the system to begin with.

You also need to extensively tune the system, requiring a few days work, and creating a vacuum within the chamber, filling it only with air.

The condensation or ice is not formed inside of the system, it is formed externally on the colder portions of the system. Therefore, the type of coolant only effects how cold it becomes.

Here is the cooler that caught my imagination a few years ago. The last I heard, it was released in Europe, but not in the US at that time. When I googled, there were no current returns, so I guess that it failed...probably due to price, which was fairly hefty.

When the Handbrake was right into overclocking, i built her a vapo cooled puter.
-58c @ idle. Nice base to up the ante for more speed.

Pulled it to bits some time ago, but haven't got around to rebuild it as she doesn't o/c much these days.

So if it was -58*c at Idle, what temp would it be when over clocked, and how much could you over clock it too?

That's a very interesting idea. I would try it, not sure I have the $$ or the expertise to do it though.

I kinda got sucked into this, and spent a while researching it, just looking at stuff on the net.

With a little help, a couple hundred bucks, and all the tools I need, I could probably build a functioning one.
I also really want to try as well.

I saw the pricing on prebuilt units, and they are just not worth it. I would much rather just buy a small refrigerator and scrap it for the parts. (200 or so vs almost 1000)
I would have to go buy a cheap computer to test it as well though.

I wonder.... Would it be possible to use the whole CASE as the evaporator? Get a nice looking case (or build your own) and completely seal it. Then plug the evaporator into one end and the condenser into the other, and turn it on...
That seems like the ultimate cooling system to me.
Might be tough with a CD/DVD drive, and the PSU, but you could create a sealed opening to run power through and external drives.

The great part is that there is no water, so you do not need to worry about insulating anything (just don't smoke next to it if there is a leak!!!!).

Have a talk to Kayl...overclockers au...he is the guy building my phase change system..you will need to register and then PM him...if he is willing he can probably help you with information

Depends on the CPU...can't say anything about temps but Kayl at Overclockers au is getting 5.2 ghz stable out of a 980 i7 (don't quote me on the CPU but I believe that's what he's playing with atm)
