Acer Aspire X1300 Desktop PC rear view,
http://support.acer.com/acerpanam/desktop/2009/acer/aspire/AspireX1300/AspireX1300rv.shtmlTo the right of the Numbers 2 and 4 is a handle formed out of the Side Panel. This formed place is to put your fingers. The Side Panel is pulled towards the Back of the computer, using this handle.
First, there are two Philips head screws to remove from the back of the Side Panel.
One is right above the formed handle.
The other is located towards the bottom. The line from the Number 5 goes right across the top of this screw.
Make SURE computer is unplugged from power, and Anti-Static Precautions are observed BEFORE reaching inside the computer.
For additional questions please post in a Comment.
