The Lian Li O11 Vision is the objective winner of this comparison, securing more category victories across the evaluated specifications. While the Corsair 4000D RS Frame holds a significant advantage in its cooling configuration by offering 100% more included fans, the Lian Li O11 Vision provides a superior storage capacity. Specifically, the Lian Li O11 Vision features a 100% advantage in available 2.5" bays, making it the more versatile option for users requiring extensive drive support.

Users who prioritize out-of-the-box cooling performance should select the Corsair 4000D RS Frame to benefit from its doubled fan count. Conversely, the Lian Li O11 Vision is the ideal choice for builders who need to accommodate a higher number of 2.5" drives within their system. By choosing based on these specific hardware advantages, you can ensure your selected case aligns with your primary requirements for either thermal management or internal storage expansion.
