Final answer:
Raised screw holes or standoffs are used to mount the motherboard inside a computer case to prevent electrical shorts, provide better cooling through air circulation, and ensure stability and alignment of the motherboard with other components.
Step-by-step explanation:
The purpose of raised screw holes or standoffs installed between the motherboard and the case is to prevent physical contact between the motherboard and the metal casing of the computer. This is important because it helps to avoid electrical shorts which can damage the delicate electronic components on the motherboard.
Standoffs elevate the motherboard, ensuring that there's enough space for air circulation, which contributes to better cooling of the computer's components. Additionally, they provide a secure and stable platform for the motherboard, keeping it aligned with other components such as the expansion slots and rear I/O ports.
Overall, using standoffs is a critical step during the installation of a motherboard to maintain the longevity and functionality of a computer.
