The Antec Flux Pro is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most impactful advantage is the inclusion of 3.5" drive bays, which represents a 100% improvement over the alternative. This superior capacity for larger storage drives makes the Antec Flux Pro the more versatile option for users prioritizing high-density mechanical storage configurations within their system build.

Users who require extensive storage for large files should choose the Antec Flux Pro for its superior 3.5" drive capacity. Conversely, the Phanteks NV5 is the better selection for builders who prioritize solid-state storage, as it offers a 100% advantage in 2.5" drive bays. Selecting between these two cases depends entirely on whether your specific build demands more room for traditional hard drives or a higher quantity of smaller form-factor drives.
