Drawer Installation Method

3-4 Upgrading the Computer
When installing the computer chassis in a drawer, the following
conditions must be met to ensure proper air flow:
At least three inches (7.6 cm) of clear space between the
back of the drawer and anything behind it, such as a wall or
the back panel of a desk.
At least two 2-inch (5.1-cm) diameter holes in the back of
the drawer. One hole must be immediately behind the power
supply for exhaust air, and the other should be used for
routing the cables.
CAUTION:
Cables should not be run through the exhaust air
hole.
At least nine holes in the front drawer panel or in the bottom
of the drawer in front of the chassis for fresh air intake. The
diameter of the holes must be between 0.38 and 0.5 inch
(1.0 and 1.3 cm).
If vent holes are located in the bottom of the mounting
drawer, allow at least one inch of clear space below the
drawer to ensure proper air flow.
At least one inch of clear space above the top of the chassis.
