The Phanteks NV5 is the objective winner of this comparison, securing more category victories across the evaluated specifications. Its most significant advantage over the Corsair 2500D Airflow is the inclusion of fans, which provides a 100% improvement in out-of-the-box cooling hardware. While both cases offer comparable features in several areas, the Phanteks NV5 leads the overall technical assessment by outperforming its competitor in four distinct specification fields.

Users prioritizing immediate thermal readiness should choose the Phanteks NV5 for its superior fan configuration. Conversely, the Corsair 2500D Airflow is the better option for builders requiring high-capacity storage, as it offers a 100% advantage in 3.5-inch drive bay support. Select the Phanteks NV5 if you want a pre-equipped cooling solution, or opt for the Corsair 2500D Airflow if your primary objective is maximizing internal drive storage for your system build.
