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

tray. Note: some components are very close to the mounting holes. Please take
precautionary measures to avoid damaging these components when you install
the motherboard to the chassis.
