Motherboard layout

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.

Ensure that you install the motherboard into the chassis in the correct orientation. The edge

with external ports goes to the rear part of the chassis.
