That is actualy the Coolermaster V6 not the Hyper 212+
The V6 is covered top in plastic where the Hyper 212+ is open, also the Hyper 212+ has copper pipes coming out the top.
Another difference the V6 has copper base, Hyper 212+ has silver aliminium
Practical or not, I'd love to see them produce these! Not mass, but maybe make them as demanded. This would be a really cool way to have a file/media server without having to leave your actual PC on all the time!
