Micro-ATX cases are compact computer enclosures designed to accommodate Micro-ATX motherboards, which are smaller than standard ATX boards. These cases typically measure around 9.6 x 9.6 inches, allowing for a more space-efficient build while still providing enough room for essential components like graphics cards, power supplies, and storage drives. Due to their smaller size, Micro-ATX cases are popular for budget builds and compact gaming systems. They often feature multiple expansion slots and drive bays, making them versatile for various configurations. Additionally, many models offer good airflow and cooling options, ensuring optimal performance in a smaller footprint.
