1.5.2 Placement direction
When installing the motherboard to the chassis, make sure to place it in the correct
orientation. The edge with external ports goes to the rear part of the chassis as

the CPU and modular components before fixing the motherboard inside the case
frame.
1.5.3 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 may damage the motherboard.
WARNING! Unplug the power cord before installing the motherboard. Failure to
do so may cause you physical injury and damage Motherboard components.
