Mini tower cases are compact computer enclosures designed to house essential components like the motherboard, power supply, and storage drives. They typically have a height of around 15 to 20 inches, making them smaller than standard tower cases but larger than small form factor cases. This size allows for a balance between space-saving design and sufficient room for hardware upgrades. These cases often support ATX or microATX motherboards, providing flexibility for various builds. Mini tower cases usually feature multiple drive bays and expansion slots, allowing users to install additional components like graphics cards and cooling systems. Their design often includes ventilation options to ensure proper airflow and cooling.
