1.5 Motherboard overview

Before you install the motherboard, study the conguration of your chassis to ensure that the

motherboard ts into it.

Ensure that you unplug the power cord before installing or removing the motherboard.

Failure to do so can cause you physical injury and damage motherboard components.

1.5.1 Placement direction

When installing the motherboard, ensure that you place it into the chassis in the correct

orientation. The edge with external ports goes to the rear part of the chassis as indicated in

the image below.

1.5.2 Screw holes

Place six screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not overtighten the screws! Doing so can damage the motherboard.
