The Lian Li A4-H2O: Compact mini case with room for high-end hardware

The Lian Li x DAN Cases A4-H2O is particularly small and fits on any desk and into any setup. With only 244 mm in height and 140 mm in width, it can be placed flexibly. The combination of steel and aluminium ensures stability while enhancing the look of your setup.

The case uses a clever sandwich layout, where the motherboard and graphics card are arranged separately. This allows for efficient use of the available space, and even large graphics cards up to 322 mm in length fit easily into the A4 H2O.

SFX and SFX-L power supplies are supported. The mini-ITX motherboard sits on one side, the graphics card on the other. This creates a powerful PC despite the small size.

Good cooling despite compact design

• Mesh surfaces on sides and top
• Optimised airflow
• Supports AiO water cooling
• Ventilated SSD mounting location

The mesh surfaces ensure a constant airflow. This keeps your hardware pleasantly cool even under heavy load. Especially when combined with an AiO water cooler, you achieve stable temperatures even during intensive use.

Easy installation of your hardware

All side panels can be completely removed. This gives you easy access to all components, making installation and cable management much easier.

Additionally, there is a mount for a 2.5-inch SSD in the base. Openings in the case help with installing large graphics cards and improve accessibility.

I/O panel with USB-C and PCIe 5.0

The case features a well-equipped I/O panel on the side. There you will find the power button as well as USB-C, USB-A, and audio ports. A PCIe 5.0 riser cable is already included for the graphics card, enabling high data rates.
