what is the main function of a computer case?

The main function of a computer case is to provide a protective enclosure that houses and supports all the vital internal components of a computer, such as the motherboard, CPU, power supply, storage drives, and expansion cards. It protects these components from physical damage, dust, moisture, electromagnetic interference, and helps manage heat by facilitating cooling and airflow. Additionally, the case helps organize and secure all parts firmly in place, contributes to proper cable management, and often includes panel switches and indicators for easy operation and monitoring of the computer system.
