Thecompact Lian Li A4-H2O X4 case combines elegance, compactness and performance. Compatible with mini-ITX motherboards, it features an optimised 11-litre interior space that allows it to accommodate excellent gaming components without sacrificing cooling efficiency. Its minimalist, trendy look is enhanced by the elegance of aluminium, so it's sure to win you over at first glance.
In addition to the front panel, the top, sides and back of the A4-H2O are well ventilated with a mesh. This mesh allows fresh air to enter the case. The unique design and format allows the A4-H2O to be fitted with a watercoooling kit with fans up to 55mm thick anda radiator up to 240mm long.
The additional spacers allow the graphics card to be pushed towards the side panel in order to evacuate or draw fresh air directly out of the chassis.
With the screwless top panel removable, you can quickly access your internal components to remove parts, add parts, manage your cables or just do some cleaning! A 2.5" SSD can also be attached to the bottom panel.
The result of Lian Li's ingenuity, this case stands out from the current production by its very pure line, made of aluminium mesh. You'll be able to build a sleek, compact and discreet configuration, capable of delivering enough spectacular power to meet all your needs, whether they are related to your leisure or your professional activity.
The case's tiered layout allows for the installation of a 322mm graphics card to fit in, and in conjunction with a PCIe 4.0 mounting cable, the graphics card is located behind the motherboard and leaves room for a 240 mm watercooling radiator at the top of the case. The bottom, side and top mesh panels ensure that components are cooled directly with the fresh air supply.

High-quality, sober mini itx case with clear instructions and very simple assembly. It allows the use of watercooling for the processor, which is essential for gaming or any other software that heats up the processor.
I'd highly recommend it for anyone who wants a sober case that doesn't take up too much space but still allows you to put in a powerful configuration.
