Looking at the PC 011 I'm not a fan of those cases due to no fans in the front and in my opinion poor airflow/design.
That's the whole point of Lian Li moving them to side intake.
For folks who are into those minimalist designs that love to choke off front fan intake: NZXT H500, Phanteks P300(nonA), Corsair Carbide 175R, etc...
Just move the fans and the grille to the side - no problems.
Both the O11 Dynamic and XL pass cooling tests with flying colors - the bottom is the weakest(airflow), but the side and top more than make up for it.
