A mid-tower case is a type of computer chassis that provides a balance between size and expandability. Typically, it stands about 15 to 20 inches tall and can accommodate standard ATX motherboards, along with various components like graphics cards and storage drives. This size makes it suitable for both gaming and general-purpose computers. Mid-tower cases often feature multiple drive bays and expansion slots, allowing users to customize their systems easily. They also provide adequate airflow and cooling options, which are essential for maintaining optimal performance. Many models come with pre-installed fans and support for additional cooling solutions, such as liquid cooling systems.
