There are two things that I like about the PC6077 in regards to the rear of the case. First and foremost is that second 80mm fan. The space is there and Lian Li wisely put a second rear exhaust fan in their 6077 series. Lian Li also modified the fan holes in the rear. If you look closely at this rear shot you can see that the grill portion of the fan hole is slightly raised from being flush with the rear of the case.
