The Phanteks NV7 is the objective winner of this comparison, securing more category victories across the evaluated specifications. While the Lian Li O11 Air Mini holds a significant advantage by providing 100% more included fans, the Phanteks NV7 distinguishes itself with a superior maximum power supply unit length, offering 39% more capacity in that specific area. This structural edge makes the Phanteks NV7 the more versatile option for accommodating larger power components within the chassis.

Users prioritizing out-of-the-box cooling readiness should select the Lian Li O11 Air Mini, as its inclusion of additional fans provides immediate utility. Conversely, those planning to utilize high-capacity or physically larger power supplies should choose the Phanteks NV7 to take advantage of its increased internal clearance. By aligning your specific hardware requirements with these distinct physical advantages, you can ensure the selected case properly supports your intended build configuration.
