Which component typically requires grounding to prevent static charges?

Grounding is essential for preventing static charges, particularly in components that can accumulate or be sensitive to static electricity. In this context, cathode ray tubes (CRTs) are particularly vulnerable due to their design and operation. CRTs involve high-voltage components and can generate static electricity easily. This static charge can not only interfere with the proper functioning of the device but also pose a risk of electrical shock or damaging the CRT itself.

Grounding helps to dissipate any accumulated static charge safely, ensuring that the device operates correctly and reducing the risk of damage. While other components like hard drives, motherboards, and fans may also require precautions against static electricity, the CRT's specific need for grounding relates to its construction and functionality, making it the primary choice in this scenario.
