Economic Footprint
The Lian Li x DAN Case A4-H2O is the ultimate celebration of the small form factor case. This Mini-ITX chassis has an incredibly small footprint, making it ideal for use as either a gaming PC or a console alternative. With its robust steel interior and sand-blasted aluminium panelling, this is a sleek case with a premium finish. At just 244mm tall and 140mm wide, this case effortlessly integrates within any gaming environment.
Sandwich Layout
To maximise on hardware, the Lian Li x DAN Case A4-H2O features an intelligent sandwich layout design. Each area is specifically designed to cater for hardware that goes beyond the expectation of the Mini-ITX form factor. This chassis can hold an SFX power supply as standard or, alternatively, the mounting bracket can be removed to accommodate for an SFX-L PSU. The motherboard is mounted on the left-hand side of the middle divider, with support for the Mini-ITX format only. Behind this, there is a dedicated area that allows for triple-slot graphics cards up to 322mm long.
A truly remarkable feat, the Lian Li x DAN Case A4-H2O does all this with space for a 240mm radiator as part of an AiO cooling loop, with a CPU cooler up to 55mm tall. Under the top panel, there is a fan bracket that can be removed and replaced with a 240mm radiator, up to 55mm thick. Unlike its predecessor, the A4-SFX, this case is fully capable of water cooling your high-end hardware.
Ease of Use
With so much going on in a small space, to make installation easier every panel on the Lian Li x DAN Case A4-H2O can be removed. This grants greater access to the interior, enabling you to manage cables and instal hardware with the greatest of ease. Additionally, the steel framework features an opening to aid in mounting longer GPUs. Upon the bottom panel, there is a mounting bracket for a 2.5” SSD, with ventilation placed beneath to prevent the hardware from overheating.
There is ample ventilation throughout the Lian Li x DAN Case A4-H2O thanks to the fine mesh featured on the side and top panels. Promoting outstanding natural airflow, this will work perfectly with the AiO cooler to keep your gaming PC at optimum temperature.
Choices
The Lian Li x DAN Case A4-H2O comes in two colours. This model is black, with the other choice being silver. What’s more, as the GPU can only be mounted vertically a PCIe riser cable is included with the case. Choose between the industry standard PCIe 3.0 or next-gen PCIe 4.0, depending on the needs of your graphics card. This model comes with the PCIe 3.0 riser cable that can be discretely tucked behind the motherboard when installing.
Connectivity
In a stylish recess, the I/O panel rests on the left-hand side of the Lian Li x DAN Case A4-H20. At the top is a premium-grade power button, whilst the bottom plays host to one USB 3.1 Type C, one USB 3.0 Type A, and two jacks dedicated to microphones and audio.
