What risk may increase if the system-unit case is left open?

Answer and explanation

Correct answer: Risk of dust and physical damage

A closed system-unit case acts as a protective enclosure for internal parts. Leaving it open exposes fans, circuit boards, and connectors to dust, accidental contact, spills, and foreign objects. Therefore, option A is correct. An open case does not update software, increase RAM capacity, or guarantee faster networking; those outcomes depend on software, hardware, and network conditions.
