Can I use dry ice to cool c?opper piping

[Derek Foster]

So I'm wanting to build a custom loop and case around some computer parts I plan on buying in a month or so.

So here's my idea. I'm going to have a strong pump pulling from 3 small reservoirs. From the pump the liquid travels to 3 240 rads stacked on each other with fans in between and on the outside of each. The liquid will travel from each rad and to there respective blocks (GPU, Mobo+CPU, and RAM). The liquid then travels from each block into a respective reservoir.
The pipes are acrylic.

I'm thinking of having the liquid travel through fairly thin copper piping (Turning a single acrylic line into about 5 copper lines) and having the thin copper piping in a small insulated room (The size of a small power supply maybe) and packing dry ice around the piping when I feel like benchmarking. Another though is making the room a tank that contains salt water (Only a quarter full of salt water) and packing the dry ice in and have the salt water more evenly cool the copper piping.

Can I use my copper pipe room idea for more extreme overclocking on a water loop?
Should I use an antifreeze based liquid for this to avoid freezing the liquid?

Let me know of any concerns you guys have.
Look forward to comments guys, I think this is an interesting idea I have (good or bad is a personal decision).

This build will not take place for a few months. Want to make sure I think everything through before I get starter.

I'd recommend just do the usual tubes pump rads... doing all those dry ice and salt water is just too much work for little amount of time unless you manage to get it to last a year.... That salt will "probably" cause problems like corrosion or stacks. If you do the salt thing then I recommend running the pump 24/7 but corrosion could occur...

First, the rads work both ways. What I mean is, typically rads are used to cool the water down. In your case, the water will be cooler than the ambient air, meaning your rads will actually warm the water up. A much better idea would be to use quick disconnects to allow you to connect either the rads or the icebox thing.
Second problem is condensation. If you are cooling down below the ambient air temperature, there is the possibility of condensation forming (think about what happens on the outside of a glass of ice water on a warm day). This is obviously very bad for your computer unless you take steps to address it.
Third, why dry ice? Why not regular ice? Much easier to use, get, store, don't have to worry about chilling pc components below their rated temp, etc.
Why copper pipe? Why not just have your alternate loop go to a small rad that is submerged in your icebox?

I actually saw a guy do something similar with his loop. the Rad was stored externally in a fish tank. No fans on the Rad obviously but the tank did have a pump to circulate the water so the Rad cooled off very rapidly before the coolant continued on its way back to the Res and through the loop again. He seemed to have good results with it. I have no idea what his maintenance is like because I have to imagine the Radiator corrodes pretty quickly being submerged in water 24/7.
