Before you unplug and open the tower
Before you begin to upgrade or replace your computer’s
hardware, it’s important to know that the tower contains
replaceable components and several open connectors
and bays. You can add or replace adapter cards, drives,
and some system board components in the tower.
If you take the time to plan your hardware changes, you
can reduce the effort required to complete your work.
You can avoid repeated handling of some hardware
components and you can anticipate, and perhaps
prevent, some online configuration.
