Disassembly Instructions
This document contains step-by-step disassembly instructions for the FlexATXChassis. The
instructions are clarified by images of the part that is being removed or disassembled.
Furthermore, the screws that are removed are shown next to the image of the parts
themselves.
When disassembling the system unit, follow these general rules.
nDo not disassemble the system into parts that are smaller than those
specified in the instructions.
nLabel all removed connectors. Note where the connector goes and in what
position it was installed.
nTurn off the power and disconnect all power and all options.
Electrostatic discharge can damage computer components.
