2.2 Motherboard overview
Before you install the motherboard, study the configuration of your chassis to ensure that the
motherboard fits into it.
To optimize the motherboard features, we highly recommend that you install it in a micro ATX
1.2 compliant chassis.
2.2.1 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.
2.2.2 Screw holes
Place eight (8) 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.
Ensure to unplug the chassis power cord before installing or removing the motherboard.
Failure to do so can cause you physical injury and damage motherboard components!
