The Corsair 5000D Airflow is the objective winner of this comparison, securing more category victories across the evaluated specifications. Its most significant advantage lies in storage capacity, as the Corsair 5000D Airflow offers 100% more 2.5-inch drive bays than its competitor. This hardware configuration provides a clear edge for users prioritizing internal drive expansion and high-density storage setups within their system build.

Users who require extensive storage space for multiple solid-state drives should choose the Corsair 5000D Airflow for its superior bay count. Conversely, those who prefer a ready-to-use cooling solution should select the Phanteks G400A, which provides a 100% advantage in the number of included fans. By prioritizing either storage flexibility or out-of-the-box airflow components, builders can align their specific hardware needs with the distinct strengths of these two cases.
