Chapter 5: Chassis Setup and Maintenance

Permanent and Optional Standoffs

Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC748 chassis packaging includes optional standoffs
(hexagon shaped posts). These standoffs accept the rounded Phillips head screws
included in the SC748 accessories packaging.
