LianLi Computer Cases A4-H2O X4 BLACK Editorial Review
Title: Lian Li A4-H20 X4 - Small case - Mini ITX The Lian Li A4-H20 X4 is a compact and straightforward small case designed for Mini ITX builds. It stands apart from other sandwich designs by being readily available for purchase without the need for waiting lists or crowdfunding campaigns.

The material and Construction are commended, making it a great option for Mini ITX builds. However, some users have experienced issues, such as broken tabs on the top and side panels.

It may require some modifications for optimal cooling, but it provides a compact and straightforward option for those seeking an ITX build.
