The Phanteks Eclipse P500A is the objective winner of this comparison, securing more category victories across the evaluated specifications. Its most significant advantage over the competition is a 50% higher capacity for 2.5" drive bays, providing superior flexibility for users prioritizing solid-state storage density. While the Lian Li Lancool 216 offers its own distinct benefits, the Phanteks Eclipse P500A demonstrates a more robust overall configuration based on the measured technical criteria.

Users who require extensive 2.5" storage support should choose the Phanteks Eclipse P500A to maximize their internal drive capacity. Conversely, those who prioritize mechanical storage needs should opt for the Lian Li Lancool 216, which provides a 50% advantage in 3.5" drive bay availability. Selecting between these two cases depends entirely on whether your build configuration relies more heavily on high-density solid-state drives or traditional mechanical hard drives.
