Apply Thermal Paste: If needed, apply a small pea-sized amount of thermal paste onto the center of the CPU.
Attach Cooler: Align the cooler with the mounting holes. Follow the cooler's instructions to secure it properly to the motherboard (it may involve clips or backplate installation).
Connect Fan: Plug the CPU cooler's fan cable into the CPU_FAN header on the motherboard.
Install Standoffs: Screw standoffs (small metal spacers) into corresponding holes in your case. These ensure the motherboard doesn't short on the case itself.
Align Motherboard: Position the motherboard with its rear ports aligning with the I/O shield slot on your case.
Install Screws: Gently screw the motherboard into the standoffs. Avoid over-tightening.

Locate PSU Mount: Most cases have PSU mounts at the bottom.
Insert and Secure: Slide the PSU into place and fasten it with screws.
Route Cables (Optional): Some cases provide space for managing cables behind the motherboard. Start routing the main power cables neatly if you intend to do this.
Consult Manuals: Find the front panel header on the motherboard (small pins usually located at the bottom). Refer to both the case and motherboard manuals for accurate connections.
Connect Wires: Carefully connect the power switch, reset switch, power LED, hard drive LED, and other case connectors to the correct pins.
Cable Management (Optional): Use cable ties to route and organize cables for better airflow and aesthetics.
Close the Case: Put the side panels back on and secure them.
Connect Peripherals: Plug in the monitor, keyboard, mouse, and power cord.
