Removing and Replacing the Side Panel
To Remove the Side Panel
You are only required to remove the side panel of the PC when removing
or replacing 5.25 inch devices (such as CD-ROM, CD-RW, DVD-ROM or
Zip drives) in the upper expansion shelves.
1 Once the main cover has been removed, loosen the screw on the side
panel.
2 Slide the side panel back by about 2 cm (0.6 inches).
3 Lift the side panel up and off the PC.
To Replace the Side Panel
1 Lower the side panel onto the PC, making sure that the inside of the
panel fits correctly into the guide rail. Leave a gap of about 2 cm (0.6
inches) between the panel and the front of the PC.
2 When you are sure that the inside of the panel fits correctly into the
guide rail, slide the panel towards the front of the PC.
3 Tighten the screw that holds the panel in place.
