Which feature would indicate when a system case cover is removed?

The feature that indicates when a system case cover is removed is known as chassis intrusion detection. This system is designed to enhance the security of the computer by alerting the user or administrator when the case is opened. It typically involves a switch or sensor that is triggered when the cover is removed, signaling that unauthorized access may have occurred.

This feature is particularly important in environments where the physical security of the hardware is crucial, such as in corporate settings or data centers, as it helps track potential tampering or theft. The alarms or notifications generated by chassis intrusion detection can also play a significant role in maintaining the integrity of the system and addressing security concerns promptly.

Other features, such as a power supply unit, thermal sensors, or overheating alerts, serve different purposes. For instance, a power supply unit supplies power to the components, thermal sensors monitor heat levels, and overheating alerts warn of excessive temperature conditions. While all these components contribute to the overall functioning and safety of a computer system, they do not specifically indicate cover removal like chassis intrusion detection does.
