Mini ITX cases are compact computer enclosures designed to house Mini ITX motherboards, which are smaller than standard ATX boards. These cases are ideal for building space-saving PCs, making them popular for home theater systems, gaming setups, and small office environments. Their compact size often limits the number of components that can be installed, but many models still support powerful hardware. Despite their small footprint, Mini ITX cases come in various designs and styles, allowing users to choose based on aesthetics and functionality. They typically feature efficient cooling solutions and can accommodate essential components like graphics cards and storage drives, ensuring a balance between size and performance.
