A Mini-ITX case is a compact computer case designed to house a Mini-ITX motherboard, which is smaller than standard ATX motherboards. These cases are popular for building small form factor (SFF) PCs, making them ideal for users with limited space or those who prefer a minimalist setup. They typically support fewer components than larger cases but can still accommodate essential hardware like a CPU, RAM, and a graphics card. Despite their size, many Mini-ITX cases offer various features, such as efficient cooling solutions and cable management options. They are often used for home theater PCs (HTPCs) or gaming systems, providing a balance between performance and space efficiency. Users can find a range of designs, from sleek and modern to more traditional styles, catering to different aesthetic preferences.
