ASUS PP-DLW motherboard user guide 2-1
2.1 Motherboard installation
Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. The PP-DLW uses the extended
ATX form factor that measures 12 in x 10.5 in (30.5 cm x 26.7 cm).
Do not overtighten the screws! Doing so may damage the
motherboard.
2.1.1 Placement direction
When installing the motherboard, make sure 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.
2.1.2 Screw holes
Place 9 screws into the holes indicated by circles to secure the
motherboard to the chassis.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause you physical injury and
damage motherboard components.
