I've heard of some home computers that were put to the test in freezers, but I have heard of this as well. Cool Stuff, can't wait to see what happens when we see this kind of technology in our cell phones.
I can't see this taking off any further than for the 'eXtreme' people. Cool idea to figure out a way to mass produce these in an aesthetically way. I messed around with water cooling years ago when I thought I was cool.
There's nothing new here that's going to circumvent Moore's Law, they just figured out a nice way of doing some neat cooling. As unfortunate as that may be.
