Item Description

The A4-H2O packs serious capability into an 11-liter footprint, making it one of the smallest cases available while still handling triple-slot GPUs and 240mm AIO liquid cooling. The aluminum exterior comes in black or silver with a minimalist design that works well in living rooms or on a desk. Extensive mesh ventilation on all sides keeps thermals in check without sacrificing aesthetics. What makes this case unique is its sandwich layout, which mounts the GPU behind the motherboard to optimize airflow and space efficiency. The removable front panel creates a wide opening that makes installing graphics cards up to 322mm straightforward, even with their triple-slot coolers. A removable top bracket handles 240mm radiators with up to 55mm total thickness (radiator plus fans), so you can fit most popular AIO configurations without modifications. The interior is SPCC steel, providing durability despite the compact size. Compatibility covers both SFX and SFX-L power supplies, and the case includes a pre-routed power cord extension that prevents cables from tangling with other components during installation. This attention to detail makes the build process less frustrating in a tight space. The A4-H2O is the result of collaboration between Lian Li and Daniel Hansen of DAN Cases, combining expertise from both parties into a case that balances form and function for enthusiasts who value compact builds without cutting corners on performance or cooling capacity.
