Micro-ATX motherboards are a type of computer motherboard that measure 244 x 244 mm (9.6 x 9.6 inches). They are designed to fit in smaller cases while still providing essential features for building a functional computer. Micro-ATX boards typically have fewer expansion slots than their larger counterparts, such as ATX motherboards, but they still support a variety of components, including CPUs, RAM, and graphics cards. These motherboards are popular for budget builds and compact systems, offering a good balance between size and functionality. They usually include multiple ports for connectivity, such as USB and HDMI, making them versatile for different applications. Micro-ATX motherboards are ideal for users who want a smaller form factor without sacrificing performance.
