The Hyte Y70 is the objective winner of this comparison, securing a lead in four out of eight measured specifications. Its most significant advantage is the support for a larger maximum radiator size, which provides 29% more capacity for liquid cooling configurations than the alternative. This superior radiator compatibility makes it the more versatile choice for users prioritizing high-end thermal management solutions and complex custom loops within their system builds.

The Lian Li O11 Air Mini is the better option for users who prioritize value and convenience, as it offers 100% more included fans than the Hyte Y70. Those who prefer a streamlined assembly process without the immediate need to purchase additional cooling hardware should select the Lian Li O11 Air Mini. Conversely, enthusiasts requiring maximum radiator support for advanced cooling setups should choose the Hyte Y70 to accommodate their specific hardware requirements.
