Great case but if you mount an 240/280mm AIO rad in the front, you will inevitably shorten the life of the pump due to the fact the air at the top of the cooling system is now effectively in the pump/cpu housing.
A top mounted 140mm single fan&rad aio at the top is my best recommendation.
Additionally if you are mounting fans in the front of the case, make sure the fans are physically inside rather than outside the case housing. Otherwise the gap between the fan & the front shield is too small, strangling the case for airflow.
I have since purchased the P300A front panel which is mesh, instead of solid metal, allowing substantial airflow for my sandwiched push pull 240mm front mount AIO, allowing it to function perfectly.
