Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fi t 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 mother-
board to the chassis. Make sure that the metal standoffs click in or are screwed in
tightly. Then use a screwdriver to secure the motherboard onto the motherboard
tray. (*Note: some components are very close to the mounting holes. Please take
all necessary precautionary measures to prevent damage done to these compo-
nents when installing the motherboard into the chassis.)
