The Lian Li O11 Vision is the objective winner of this comparison, securing victory in five out of eight evaluated specifications. Its most significant advantage over the competition is its storage capacity, offering 100% more 2.5" bays for drive mounting. This superior hardware configuration makes it the more versatile choice for users prioritizing internal expansion and storage density within their system build.

Choose the Lian Li O11 Vision if your primary requirement is maximizing the number of 2.5" drives supported by your chassis. Conversely, select the NZXT H6 Flow if you prefer a case that comes ready to use out of the box, as it provides a 100% advantage in included fans. This makes the NZXT H6 Flow the more convenient option for builders who want to minimize additional component purchases during assembly.
