Review the Mac Pro's Internal Components
When you remove the Mac Pro case, you expose several of the machine's internal compon-
ents. Although you do not need to know the name and purpose of every visible component to
work with Mac Pro internally, you do need to know the location of those components you can
change: the memory modules and the hard drive. Beyond that, Mac Pro is a marvel of engin-
eering, so it is worthwhile to see how Apple managed to fit so much inside such a small
package.
A Memory
This component is the internal
random access memory
(
RAM
) that the Mac Pro pro-
cessor uses to manipulate and store data from OS X and your applications. There
are four memory slots, each of which contains a memory module. You can replace
these memory modules, as described in the next section, “
Upgrade the Memory

B Fan
Mac Pro is kept cool by a single fan at the top, which pulls air vertically through the
machine, with the hot air generated by the components expelled through the top.
