Answers: Jtroutma you got the idea.

I’m fabricating an Acrylic Cylinder about 16 inches in Diameter and about 16-18 inches in length. Inside is just the motherboard, Cpu, GPU and as Skulemate pointed out the voltage reg as heat sources. The Psu, hard drive and cd-rom are external of the cylinder. I’ve found Military spec Explosion proof Cannon plugs that’s I’ll use for the Atx power supply and 12v,5v system. Also included is atx switch and leds if I really want to.

There’s a product out their name Amp tape that’s used as a general sealant for the Telephone companies and DSL providers and provides many other uses. This tape is rubbery and is rapped around cables eg. my Video, USB 2.0, RJ45 and some others that will fit through a hole and with Silicon and other methods seal it, but the amp tape is doing most of the work in filling in those tough to get (round edges). The biggest problem so far is how to get my ATA cables outside or at least just one for my hard drive. (Hard drives don’t like the cold) I think I can do it by cutting a slot and use the amp tape combined with small acrylic plates to create a seal and some silicon.

Keyboard and mouse will be wireless, I’ve considered doing a lot more wireless things like USB and Network but the cost will be more insane than this project.

I’ll use a vacuum pump to suck out the O2 and after a short time turn on my nitro tank (Laying beside the cylinder) and purge the cylinder. Then turn the valve off to the vacuum pump, then turn off the pump and let the nitro build up pressure inside.
One of the key points is that I’m only putting 3 to 5 PSI inside nothing major. And with a Regulator I can control the amount of Nitro that goes inside. One thing to remember is that as long as I have a positive pressure inside the cylinder nothing can get inside (regular air).

Ok great now let’s just assume that this all works and I get a 99% seal nitrogen environment a little leak is ok just not a major one. Skulemate also pointed out that heat still works in a nitrogen environment absolutely correct, so I’ll be installing inside the cylinder a coil of copper tubing pumped with water. I’ll have 2X120mm fans circulating the nitro around inside. Here’s what I got for the cooling….

From a reservoir of water, water is pumped into a coil of copper tubing attached to a cold plate with has some peltiers on it, the tube comes out of the Cold coil to the coil located inside the cylinder cooling the nitrogen environment. The hot side of the pelt is cooled with tradition air-cooling and heat sinks. The tubing from the cold coil is insulated as it travels to the coil inside the cylinder just to make sure I don’t lose anything in the process. That deals with bringing the ambient air temp down to maybe +5C Not sure if I can get into the negatives but I’m guessing NO, now compare that to the +15C of the ambient air inside of a house, it’s a little but a lot.

Now I’m still deciding weather to use water cooling on my CPU, GPU, If anything I’ll go with water cooling with out support from Peltiers, that is until I can get enough money to buy good enough Pelts and a power supply that is rated for the big pelts. I may even go with traditional Air cooling for my Cpu, GPU and volt reg. Not sure at this point still need to see what kind of results I’ll get with just cooling the ambient environment. That means at least one more water Reservoir. I was also thinking that if I had my Water reservoirs in a bucket (Crude) or something I could throw in some Ice to cool the water down, and Insulate the Reservoir.

Now to the Question of Why Nitrogen?
A: Non corrosive
B: Only 4parts per million of water atoms (Regular Nitrogen, I’m not using a Spec Gas/research grade, UH+ or UHP)
C: Nitrogen won’t hold Positively Charged particles at least not a lot. Co2 tends to hold onto dust and hair and small positively charges objects.
D: It’s not Explosive in it’s natural state
E: It’s not toxic and you don’t need to put silly stickers on your car when you transport Nitrogen
F: Helium is ok, but It’s expensive due to the fact that is has to come from Decaying Hydrogen pockets from Oil wells or under the ground. Also if there was a major leak I’m not sure how many ppl would like to have silly voices at a lan party.
G: Nitro is cheap and there’s a lot of it in the Air we breathe
H: Nitrogen is easier to cool down and heat up

I think the using the Salts is a good idea, I’ll keep that in mind.

Any ways that’s the Huge spiel so far, hard to get into specifics but ya.

Hope that answers some question it was hard to get into detail before on the other post due to time. Plz give me more feed back, I love it. It's great to talk to ppl that know what I'm talking about.

I'll try to post some more Dimentional data in the next few days specifics about size and stuff.
