The Phanteks NV5 and the Thermaltake CTE C750 Air are tied in this objective comparison, as each case leads in three out of eight measured specifications. The most significant differentiator between these two options is storage capacity. The Phanteks NV5 offers a 100% advantage in 2.5" drive bays, while the Thermaltake CTE C750 Air provides a 100% advantage in 3.5" drive bays, making the choice dependent on your specific storage requirements.

Choose the Phanteks NV5 if your build relies heavily on smaller solid-state drives, as it doubles the available 2.5" mounting locations compared to its competitor. Conversely, select the Thermaltake CTE C750 Air if your system configuration necessitates high-capacity mechanical storage, as it doubles the 3.5" drive bay count. Both cases offer equivalent performance across the remaining measured specifications, so your decision should be driven entirely by your internal storage needs.
