11 Liters of Pure SFF Performance
The A4-H2O is a tribute to Small Form Factor (SFF) design. With a volume of just 11 liters, it is one of the smallest cases on the market that manages to combine support for triple-slot graphics cards and space for 240mm AIO liquid cooling, offering high-end computer performance in a size smaller than a console.
Smart Sandwich Layout & PCIe 5.0 Riser
The internal sandwich layout design places the graphics card behind the motherboard, optimizing space. The case includes a high-speed PCIe 5.0 riser cable (up to 32 GT/s), ensuring maximum compatibility with the latest generations of GPUs, while allowing direct cooling of the components through the mesh panels.
Optimized Cooling and 240mm Water Cooling
Despite its small size, the A4-H2O is "built" for low temperatures. It features a removable top bracket for easy installation of a 240mm radiator (up to 55mm thick including the fans). The side, top, and rear panels are made of fine mesh, allowing continuous intake of fresh air.
Compatibility with Triple-Slot GPUs up to 322mm
Its spacious interior supports triple-slot graphics cards with a length of up to 322mm. In fact, removing the front panel reveals an opening that makes it easier to insert large cards, while there are special standoffs that bring 2-slot cards closer to the mesh panel for better ventilation.
Minimalist Design from Premium Aluminum
Available in black or silver, the A4-H2O features an exterior made of premium aluminum that fits any office or living room setup. The minimalist design by LIAN LI x DAN Cases offers an elegant appearance, while its dimensions (326 x 140 x 244 mm) make it ideal for those who want a clean and spacious workspace.
Easy Installation and Cable Management
All panels (top, bottom, sides, front) are fully removable for maximum access during setup. The case supports SFX and SFX-L power supplies and includes a pre-installed power extension cable. The removable bottom panel facilitates cable management and allows the installation of a 2.5” SSD drive.
