The Montech KING 95 Pro is the objective winner of this comparison, securing seven out of eight total specification categories. Its most significant advantage over the Lian Li A4-H2O is its maximum cooler height, which is 218% greater. While the Lian Li A4-H2O holds a 50% advantage in the number of available 2.5-inch drive bays, it falls behind in the majority of measured technical specifications compared to the Montech KING 95 Pro.

Users prioritizing extensive cooling compatibility should choose the Montech KING 95 Pro, as it offers vastly superior clearance for large thermal solutions. Conversely, the Lian Li A4-H2O is the better selection for builders who specifically require a higher capacity for 2.5-inch storage drives within their system configuration. Select the former for hardware flexibility or the latter if your primary build requirement is maximizing internal drive mounting options.
