The Lian Li Lancool 216 is the objective winner of this comparison, securing more category victories across the evaluated specifications. Its most significant advantage over the be quiet! Pure Base 500DX is its capacity for 3.5" storage drives, offering a 50% increase in space for these components. While both cases share several identical specifications, the Lian Li Lancool 216 provides a more robust foundation for users requiring higher density for larger mechanical hard drives.

Users who prioritize mass storage capacity for 3.5" drives should choose the Lian Li Lancool 216 for its superior bay count. Conversely, the be quiet! Pure Base 500DX is the better option for builders who rely heavily on smaller form factor storage, as it provides a 150% advantage in 2.5" bay availability. Selecting between these two cases depends entirely on whether your specific build configuration requires more room for high-capacity mechanical drives or compact solid-state storage.
