What should you place between the motherboard and the case during installation?

1. Spacers

2. Stand-offs

3. Thermal paste

4. Insulation pads

The correct answer is: Stand-offs

During the installation of a motherboard into a computer case, it is essential to use stand-offs. Stand-offs are small metallic or plastic risers that keep the motherboard elevated above the case’s surface. This elevation is crucial for several reasons. First, stand-offs prevent electrical short circuits. If the motherboard were to sit directly against the metal case, there could be unintended contact with components on the back of the motherboard, which could lead to shorts and disrupt the electrical integrity of the system. By using stand-offs, you create a safe space that ensures the motherboard is insulated from the case. Second, stand-offs facilitate airflow beneath the motherboard, which can help in cooling. Proper airflow is critical in a PC setup, as it can significantly impact the thermal performance of the components. Finally, stand-offs also provide stability, ensuring that the motherboard is securely mounted within the case and reducing the risk of it moving or vibrating during operation, which can affect the connections and solder points on the motherboard. Using spacers might sound similar, but they do not serve the same purpose. Thermal paste is used for CPU installation to fill gaps and improve heat transfer, while insulation pads are not standard for motherboard installation. Thus, stand-offs are the correct choice for securing the motherboard properly within
