A bit more digging has revealed that the monster twin-tower DFI LANParty branded cooler we spotted last week isn't a creation of Thermalrights. Rather, it is based off a full production model from a company many wouldn't have heard of before; Prolimatech. The cooler's currently available in Europe at a cost of 59.90 EUR.
A little bit more can now be learnt about the cooler. It runs dimensions of 130×74x158.7mm, weighing in at 790g. It doesn't come with any fans, but one or two 120mm fans can be mounted on either side.
It's all speculative at the moment but it's expected the cooler will be identical once DFI start handing it out (apart from some possible aesthetic adjustments) and it may possibly be bundled with select high-end motherboards.
