I've seen kits where someone takes an eclipse aio aquarium and turns it into a submersion cooling pc rig.. its kind of expensive for what it is though.
The best thing I could think of to use to make the liquid sub-ambient would be an aquarium chiller. They are rated in hp, but you can look up their btu capability too. I've seen builds where people use theres and they work, however without any load these chillers only hit about 17*c. Total loop size is measured in gallons too, 5-20 gallons is easy too do even with the 1/15hp chillers. Many use titanium coils now, fairly unreactive stuff.
If the loop is sub-ambient, then using a radiator will actually add heat to the system due to heat traveling from ambient to the loop.
Also when looking at the liquids, look at the specific heat capacity. Alcohol won't freeze light water, but won't absorb as much heat before it heats up either.
My take on it: it could be done with an aquarium chiller, but after the costs and effectiveness on cooling, you'd probably be better of with a tec plate for sub-ambient, and not submerged.
