Participants will learn how to securely mount storage drives into the designated drive bays in the computer case. This involves using screws or a tool-less mounting mechanism, depending on the case design. Next, we will cover the installation of a graphics card, which typically involves inserting it into a PCIe slot on the motherboard. The lesson also covers connecting power cables to the graphics card if required. Ensuring a snug and secure fit is vital for stability and performance, especially for heavy GPUs.
