The next step is finally placing the motherboard in the case. Fit it on its correct place (see Figure 22) and then slide it on the direction of the back of the case (see Figure 23). After the motherboard is in the correct place, screw the metallic plate where the motherboard is installed back to the case.

The final step is organizing the cables inside the case. Take a look at Figure 25 how was our PC after we installed the motherboard. You can see cables everywhere. The wires and cables must be organized in a way that they let the correct airflow inside the case to take place. Otherwise you will face overheating problems, and that's a very common mistake when assembling PCs. In Figure 26 you see our PC after we organized its cables.
