Installing the Motherboar
Note: If the motherboard has mounting holes, but don't line up with the holes
on the base and their are no slots to attach the spacers, don't worry, you
can still attach the spacers to the mounting holes. Just cut the button
portion of spacers (the spacer may be a little and hard to cut off, so be
careful of your hands). In this way you can still attach the motherboard
to the base without worrying about short circuits.
Sometimes you may need to use the plastics spring for isolate the screw from
motherboard PCB surface, because the circuit wire may be near by the hole.
Be careful don't let the screw to contact any printed circuit wire and parts on
PCB that near by the fixing hole, otherwise it may damage the board or cause
the board malfunction.
