The NZXT H9 Flow is the objective winner of this comparison, securing more category victories across the evaluated specifications. Its most significant advantage over the ASUS Prime AP201 is the inclusion of fans, which represents a 100% improvement in out-of-the-box cooling hardware. While both cases offer distinct design choices, the NZXT H9 Flow provides a more comprehensive hardware package for users who prioritize pre-installed components for their system build.

Choose the ASUS Prime AP201 if your primary goal is to minimize initial costs, as it holds a 45% advantage in MSRP. This option is ideal for budget-conscious builders who prefer to select their own cooling solutions. Conversely, select the NZXT H9 Flow if you prefer a case that comes fully equipped with fans, reducing the need for additional purchases and simplifying the assembly process for your new PC.
