Installing the Motherboard
Review the documentation that came with your motherboard. Become familiar 1.
with component placement, requirements, precautions, and cable connec-
tions.
Remove the four screws which mount the middle bracket onto the chassis as 2.
illustrated below. (Unplug the fan connectors from the original motherboard if
necessary) and lift the middle bracket up and out of the chassis.

Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC848 chassis includes permanent standoffs in locations
used by most motherboards. These standoffs are included in the SC848 acces-
sories 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 standoff through the bottom
the chassis and secure it with a wrench, with the rounded end upward.
