How can you say that?
Settles it, getting one and comparing it to the PC7+II and the Savrow SR71.
It can not have the best cooling period, due to the way it uses lots of fans and no focused airflow.
If you can provide some proof to the claim that is credable then I would accept it, but just saying that without anything to back yourself up with is not really good practice.
Savrow SR71 with its hundreds of users has the lowest temperatures across computers probably for the decade consistantly, a case with more than two fans beating it to me is uncomprehendable without proof to dispute the last seven years of one chassis dominance for cooling.
There are specialist cases that can cool one particular system the best possible. No case can have the best cooling for every system; each will have its strengths and weaknesses but never be the best cooling across the board.
The best cases cool everything well, but nothing poorly.
