Installing the Motherboard
Review the documentation that came with your motherboard. Become familiar
1.
with component placement, requirements, precautions, and cable connec-
tions.
Open the chassis cover and remove the chassis from any power source.
2.
As required by your motherboard, install standoffs in any areas that do not
3.
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).
Figure 4-9: Chassis Standoffs
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC847 chassis includes permanent standoffs in locations
used by most motherboards. These standoffs accept the rounded Phillips head
screws included in the SC847 accessories packaging.
Some motherboards require additional screws for heatsinks, general components
and/or non-standard security. Optional standoffs are included to these mother-
boards. 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).
