How To Assemble A Basic Desktop PC

Step 6 Install Motherboard

To install the motherboard we need parts that should have been included with your purchased components:

• I/O Bezel is a trim panel installed in the back of the case that surrounds the interface ports on the motherboard. It should be included with the motherboard. Figure 12 shows the contents of the motherboard box.
• Standoffs are installed in the case screw holes to create a riser that separates the case and motherboard. The screws install into the standoffs as shown in figure 13. Screws and standoffs should be included with the case, but it is a good idea to order these items just in case they aren't included.

Follow these steps to install the motherboard in the case:

1. Install the I/O bezel plate into the opening in the back of the case (figure 14). It pushes in from the inside.
2. Install standoffs in the case. The standoffs screw into the motherboard mounting holes shown in figure 14. Check the screw hole locations on the motherboard for exact placement.
3. Lower the motherboard into the case and align with the I/O bezel.
4. Install the screws.

Figure 15 shows the motherboard installed in the case. It works best to leave the screws loose until all of them have been started and the board is aligned with the bezel.

Caution: To prevent damage to the motherboard it must only contact the standoffs and screws. All of the standoffs and screws must be installed.
