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 motherboard and
chassis match. Make sure that the metal standoffs click in or are screwed in tightly.

Note: some components are very close to the mounting holes. Please take
precautionary measures to prevent damage done to these components when
you install the motherboard into the chassis.
