Freezer for Computer case

it would just be smarter to make a phase change unit(basically just a compressor, evaporater, and condenser that generally uses a gas to be changed into a liquid to be cooled)

You just described all the systems that have been discussed in this thread. The only difference is where the evaporator is.

As far as building a system goes, this isn't as easy as modding a computer. It takes a bit of knowledge and a fair amount of equipment (e.g. a vacuum pump to purge the system before filling it with refrigerant). If you're going to do it definitely visit XtremeSystems, there are many people there that have done this and a decent knowledge base.
 
^^ Very true. If you dont have a refrigeration background you prob couldnt do this mod. Not to mention you have to be EPA certified to legally charge the system and to work on it with refrigerant in it.

What refrigerant would be used with this? R22 or maybe 404A but R22 is for lower temp applications.

Yes, you should be at least EPA 608 Type I certified, not just for legal reasons, but you should just have that knowledge. For refrigerants it depends on if you're going for all-out performance or just something that will work. R22 would be for a high pressure system though its being phased out since it is a HCFC. R134a would be under the "just works" category; I've even heard of people using camping propane tanks to fill their systems. I'm sure there are some 4xx mixes that would do a good job, but I'm mainly work with helium since those typical refrigerants have way too high of boiling points for my line of work.

Oh yeah a small system like this most likely wouldnt be considered high pressure. We are using 404A on our trainers at my tech center and we are able to get really low temps with it. I took the certification test about 2 weeks ago as an end of the year exam and passed it. The test is very outdated and there are alot of dates to remember about when certain refrigerants were phased out and when laws were placed. Next year in tech center we are working on heating and cooling as this year we are working on refrigeration. I have learned alot in tech center and cant wait to learn more. Haha my teacher has a bunch of R22 stashed somewere to make money off of it when it eventually gets phased out. He is going to be rich. R22 is mainly used on walk in freezers, right?

That's actually not a bad idea. You'd probably need a lot of it though to make a profit.

Yeah, I would say it's used a lot in industry. A friend of mine was doing his PhD for defrosting cycles/methods for the Blue Bunny ice cream storage plant, and I know they were using R22. I'm pretty sure a lot of large, central-air AC systems use it too though.

Yeah i'll ask him tomorrow how much he has b/c I forgot. I know hes had it for 20+ years now. Wow, im getting into this thread now. Wish I had the money b/c I would go forward with this mod/build. Lets keep these ideas going for future reference.
