In this step-by-step guide, I walk you through preparing your motherboard for a fresh PC build—including installing the CPU, cooler, RAM, and any M.2 drives—before mounting it securely in the case. Next, I show how to install a modular power supply, from attaching only the essential cables (like the 24-pin ATX and CPU power) to properly routing them for clean cable management and optimal airflow. Perfect for beginners building their first custom rig! | Re-Boot IT Solutions, Townsville.
