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 small form factor (SFF) PCs, making them popular for home theater systems, gaming setups, and portable workstations. Their reduced size allows for efficient use of space while still providing essential features. Despite their small dimensions, many Mini-ITX cases support various components, including graphics cards, power supplies, and storage drives. They often come with multiple cooling options to ensure optimal performance. Users appreciate the balance of size and functionality that these cases offer for diverse computing needs.
