The Lian Li O11 Vision is the objective winner of this comparison, securing more individual specification victories than its competitor. While both cases offer distinct design philosophies, the most impactful advantage provided by the Lian Li O11 Vision is its storage capacity, which features 100% more 2.5" bays than the Corsair 3000D Airflow. This significant increase in drive support makes the former a more versatile option for users requiring extensive internal storage configurations for their builds.

Users who prioritize out-of-the-box cooling solutions should select the Corsair 3000D Airflow, as it offers 100% more included fans than the Lian Li O11 Vision. Conversely, those who need to house multiple solid-state drives or require greater storage flexibility should choose the Lian Li O11 Vision. By focusing on these specific advantages, builders can align their hardware selection with their primary needs for either pre-installed airflow components or expanded drive bay utility.
