The ASUS Prime AP201 is the objective winner of this comparison, securing six spec victories against the single win held by the Lian Li A4-H2O. The most impactful advantage for the ASUS Prime AP201 is its maximum cooler height, which is 209% better than that of the alternative. This significant margin provides substantially more flexibility for internal component selection, making it the superior choice for users prioritizing hardware compatibility and cooling clearance within their build.

Users who require maximum support for tall cooling solutions should select the ASUS Prime AP201 to take advantage of its superior height specifications. Conversely, the Lian Li A4-H2O is the better option for builders who specifically prioritize storage capacity, as it offers a 50% advantage in the number of available 2.5-inch drive bays. Choosing between these two cases depends entirely on whether your priority is accommodating larger cooling hardware or expanding your total drive count.
