With the memory installed, you can now connect power to the CPU fan, as
shown in Figure 8-27.

The motherboard is now prepared. Place it aside for now. Use the antistatic foam
under the motherboard to make sure it's not damaged by static electricity.
FinalCasePreparation
Next, we'll complete a few final case-preparation steps to ready the case to re-
ceive the motherboard. To begin, remove the I/O shield installed in the Antec
Atlas 550 case. The easiest way to do that is to press on the outside of the I/O
shield with a tool handle, as shown in Figure 8-28, until the I/O shield pops
loose. You can discard this I/O shield.
Locate the I/O shield in the motherboard box and hold it up to the rear I/O
panel of the motherboard, as shown in Figure 8-29, to make sure that the holes
in the I/O shield correspond to the ports on the motherboard rear I/O panel.
Working from inside the case, position the I/O shield and use a tool handle to
press gently on it until it snaps into position, as shown in Figure 8-30. Be care-
ful not to bend the thin metal of the I/O shield. If necessary, use your fingers on
the outside of the I/O shield to support it while you're pressing it into position.
With the custom I/O shield installed, the next step is to determine the proper
number and location of the motherboard mounting standoffs. The ASRock
motherboard has six mounting holes. The Atlas 550 case comes with four
brass standoffs installed, only two of which are in the proper positions for the
motherboard. (The remaining two are located off to one side where they can't
contact the motherboard; you can leave those standoffs installed or remove
them, as you like.)
Locate the motherboard mounting hole positions by holding the mother-
board up to a bright light. Slide the motherboard temporarily into position in
the case to determine which of the holes in the chassis need to have standoffs
installed. We used a felt-tip pen to mark the holes in the chassis that needed
standoffs to be installed, as shown in Figure 8-31.
