Case LIAN-LI Mini-ITX A4H2OX3 PCIe 3.0 black Mini-ITX

11-Liter Form Factor

At just 11 liters, the A4-H2O is one of the smallest cases on the market that supports a three-slot GPU and has room for a 240mm AIO liquid cooler.

SIZE COMPARISON

The A4-H2O is smaller than most consoles, and its minimalist design fits any living space or entertainment center for enjoying games or movies.

Minimalist Design – Black or Silver

With a minimalist design, the A4-H2O comes with a premium aluminum finish and air filtration from nearly all sides. The A4-H2O is available in black or silver.

Sandwich Layout Design

The sandwich-style layout allows a three-slot GPU to easily fit in the compact case. Combined with a PCIe Gen. 3 or Gen. 4 riser cable, the GPU is positioned behind the motherboard, leaving room for a 240mm radiator at the top of the case. Mesh panels at the bottom, side, and top ensure direct component cooling with fresh airflow.

Fully Removable Panels

Front, side, top, and bottom panels can be easily removed to provide easier access for installation and/or cable management.

PCIe 3.0 and PCIe 4.0

The A4-H2O includes a PCIe Gen.3 or PCIe Gen. 4 riser cable for mounting the GPU vertically and positioning it behind the motherboard. The PCIe 4.0 cable supports transfer rates of 16GT/s (double the speed of PCIe 3.0). PCIe Gen.4 cables are backward compatible with PCIe Gen 3.

IO and Power

Located on the left side of the case within a recessed slot, the front IO includes a USB 3.1 Type-C port (internal Key-A), microphone port, HD-Audio port, and USB 3.0 Type-A port (internal 19-pin). At the top of the slot is the high-quality power button.
