SC846 Chassis Manual
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC846 chassis includes permanent standoffs in locations
used by most motherboards. These standoffs accept the rounded Phillips head
screws included in the SC846 accessories packaging.
Some motherboards require additional screws for heatsinks, general components
and/or non-standard security. Optional standoffs are included to these motherboards.
To use an optional standoff, you must place the hexagonal screw through the bottom
the chassis and secure the screw with the hexagon nut (rounded side up).
Installing the Motherboard
1. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, precautions, and cable connections.
2. Power down the system as described in section 4-2 and open the chassis cover
as described in Section 4-1.
3. As required by your motherboard, install standoffs in any areas that do not
have a permanent standoff. To do this:
a. Place a hexagonal standoff screw through the bottom the chassis.
b. Secure the screw with the hexagon nut (rounded side up).
