mini-ITX is a small motherboard form factor designed for compact computer systems. Measuring just 17 x 17 centimeters (6.7 x 6.7 inches), it allows for efficient use of space while still supporting essential components like a CPU, RAM, and storage. This makes it popular for building small desktop PCs, home theater systems, and gaming rigs. Despite its size, mini-ITX motherboards can offer a range of features, including multiple USB ports, integrated graphics, and support for Wi-Fi and Bluetooth. They are often used in SFF (small form factor) cases, which help create sleek and portable computing solutions without sacrificing performance.
