The Hyte Y40 emerges as the objective winner in this comparison, securing a lead across four measured specifications. Its most significant advantage is the support for larger cooling solutions, offering a 29% increase in maximum radiator capacity compared to the alternative. This superior cooling flexibility makes it the more capable choice for users prioritizing high-end thermal management and liquid cooling configurations within their system build.

The Lian Li O11 Air Mini is the preferred option for users who require extensive local storage, as it provides a 100% advantage in 3.5-inch drive bay capacity. Those who prioritize high-density data storage should select the Lian Li O11 Air Mini for its superior drive support. Conversely, builders who intend to utilize expansive radiator setups for advanced cooling should choose the Hyte Y40 to leverage its greater radiator compatibility.
