A mini-tower case is a type of computer case that is smaller than a standard tower but larger than a small form factor case. It typically accommodates standard ATX motherboards and provides enough space for essential components like a power supply, hard drives, and graphics cards. Mini-tower cases are popular for home and office use due to their compact size, which makes them easier to fit in limited spaces. These cases often come with multiple expansion slots, allowing users to add additional hardware as needed. Many mini-tower cases also feature cooling options, such as fans or vents, to help maintain optimal temperatures for the components inside. They are a practical choice for users looking for a balance between size and functionality.
