The Phanteks NV7 is the objective winner of this comparison, securing more category victories across the evaluated specifications. While both cases offer distinct design priorities, the Phanteks NV7 provides the most significant advantage in terms of hardware compatibility, boasting a 39% lead in maximum power supply unit length. This superior internal clearance allows for greater flexibility when selecting high-capacity power components compared to the Lian Li O11 Air Mini.

Users prioritizing out-of-the-box cooling efficiency should choose the Lian Li O11 Air Mini, as it features a 100% advantage in included fans. Conversely, the Phanteks NV7 is the better choice for builders who require extensive room for larger power supplies to support high-end system configurations. Selecting between these two cases depends entirely on whether your build requires immediate thermal support from pre-installed hardware or the physical space to accommodate longer power supply units.
