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.) do not use a force greater than 8 lb/inch on each mounting screw during Caution: To avoid damaging the motherboard and its components, please motherboard installation. 2-5
