Case LIAN-LI A4-H2O Mini-ITX Silver Mini ITX Color:white

A tribute to the SFF world

The A4‑H2O is an 11‑liter SFF case built in collaboration with DAN Cases, carrying forward the DAN A4‑SFX sandwich philosophy in an ultra‑compact footprint. The new generation offers improved hardware compatibility — including AIO liquid cooling — and a simpler, more convenient installation process. The result is a powerful PC in a small case, with a clean design and meticulous build quality.

11‑liter volume

Despite its tiny dimensions, the A4‑H2O supports a triple‑slot graphics card and room for a 240 mm radiator for liquid cooling. It is one of the few compact cases that deliver a smart combination of performance, airflow, and advanced cooling—without compromising on acoustics and design.

Size comparison

The A4‑H2O is smaller than most modern game consoles, so it fits naturally into entertainment centers, on sideboards, and in tight living spaces. Its minimalist design blends into any environment—gaming, work, or movie watching—without drawing unnecessary attention.

Minimalist design – black or silver

The enclosure is made of premium aluminum with generous ventilation openings around the case for efficient airflow to every component. The restrained, upscale look is offered in two finishes—black or silver—so you can easily match your PC to your space’s style.

Sandwich layout

The sandwich layout makes it possible to install a thick graphics card in a compact case, with a PCIe Gen3/Gen4 riser cable positioning the GPU behind the motherboard. This preserves space for a 240 mm radiator at the top, while mesh panels on the bottom, sides, and top ensure a direct supply of cool air to the components.

Fully removable panels

All panels—front, side, top, and bottom—detach easily for maximum access during assembly and cable management. The modular structure saves time, simplifies maintenance, and enables effortless future upgrades.

Ports and power button

In the recess on the left side, you’ll find front I/O that includes USB‑C 3.1 (internal Key‑A), a microphone jack, HD audio, and USB‑A 3.0 (internal 19‑pin). At the top of the recess sits a high‑quality power button for convenience and immediate access.

Triple‑slot GPU compatibility

Removing the front panel creates a wide opening for easily inserting large graphics cards. The interior supports cards up to three slots thick and up to 322 mm long—while maintaining efficient airflow and optimal cooling for all components.
