Lian Li A4-H2O is an 11-liter compact case, developed in collaboration with DAN Cases. Based on the original DAN A4-SFX case’s sandwich-layout concept, the A4-H2O continues the minimalist and compact design with improved compatibility (including water cooling) and simplified installation.

The 11-liter A4-H2O is one of the few small cases on the market that can accommodate a triple slot graphics card and a 240 mm water cooling system. With the included PCIe Gen 4 riser cable, the graphics card is installed behind the motherboard, leaving space for a 240 mm radiator at the top of the case. Mesh panels on the bottom, sides, and top keep the case temperatures moderate. The ports are located on the left side panel, which features a power button, USB 3.1 Type-C, USB 3.0 Type-A, HD audio, and microphone jacks.
