personally i believe that more "extreme" cooling should be much mroe mainstream then it is. There honestly isnt any reason why a water system should cost 200$, and a phase cooling system should cost 500+, when you look at the components they have it jsut shouldnt be that high. I mean, you cna get a little fridge for 100$ that works jsut like a phase change system, but is much cheaper. Also, a radiator and some water pumps shouldn;t cost what they do either. But even at the given prices, it just makes sense to use water cooling more. When you consider the huge markup that chipmakers put on the high end CPUs, getting a lower end one and overclocking it just as high makes alot more sense. If water cooling were something that was standard in PCs, then i'm sure the per unit cost coudl be more like 50$ for a standard system, but instead nowadays you have to get it seperately from ocmpanies that don't sell enough volume to really make it economical. Anyways, thats just my 2 cents...
