Yeah. I have heard it is, but from what I understood it was supposed to be comparable to some top air fans. It looks like that's not the case.
I know it has room for 4 door fans...my post said 2/4 door fans blocked due to the radiator over one of the two back fans. The radiator extends too far and you can't close the case with the other two door fans on. It is part of the LCLC setup or I would just remove it.
