3.4 Motherboard Installation

All motherboards have standard mounting holes to fit different types of chassis. Make sure
that the locations of all the mounting holes for both the motherboard and the chassis match.
Although a chassis may have both plastic and metal mounting fasteners, metal ones are
highly recommended because they ground the motherboard to the chassis. Make sure that
the metal standoffs click in or are screwed in tightly.

Location of Mounting Holes

Note 1: To avoid damaging the motherboard and its components, please do not use a force
greater than 8 lbf-in on each mounting screw during motherboard installation.
Note 2: Some components are very close to the mounting holes. Please take precautionary
measures to avoid damaging these components when installing the motherboard to the
chassis.
Note 3: If installing an M.2 long riser, instead of the standard Phillips Screw, there will need
to be a Ball Pin Screw installed at the location specified on the motherboard layout.
