Lian Li A4H2OA5 M-ITX Mini Tower Silver Case

The Lian Li A4-H2O A5 is an 11-litre small form factor enclosure developed in collaboration with DAN Cases. Drawing from the original DAN A4-SFX sandwich layout concept, it places the graphics card behind the motherboard on a dedicated riser, freeing the top compartment for a 240mm all-in-one water cooler. The result is a genuinely compact build platform that accommodates high-end components without sacrificing thermal performance. The exterior is constructed from anodised aluminium, giving the silver finish both durability and a clean aesthetic that suits a living room shelf, entertainment centre, or desktop equally well. Mesh panels on the top, sides, and bottom allow fresh air to reach components from multiple directions, while the single solid front panel keeps the profile tidy. All four main panels — front, side, top, and bottom — are fully removable, simplifying installation and cable routing. A bundled PCIe 5.0 riser cable handles the vertical GPU mount, supporting transfer rates up to 32 GT/s and remaining backward compatible with PCIe 4.0 and earlier cards. The front I/O, recessed into the left side of the chassis, provides a USB 3.1 Gen 2 Type-C port (internal Key-A header), a USB 3.0 Type-A port (internal 19-pin header), a microphone input, and an HD audio jack, topped by a premium-grade power button. Storage is handled by a single 2.5-inch SSD that mounts directly to the removable bottom panel, keeping the interior uncluttered. A pre-routed power-cable extension is included to prevent the PSU lead from conflicting with other hardware.
