It's As Easy As 2, 1, 3
Although by necessity we describe
building the system in a particular
order, you don't need to follow that
exact sequence when you build
your own system. Some steps—for
example, installing the processor
and memory before installing the
motherboard in the case—should be
taken in the sequence we describe,
because doing otherwise makes the
task more difficult or risks damaging
a component. But the exact sequence
doesn't matter for most steps. As you
build your system, it will be obvious
when sequence matters.

Before you proceed, make sure you have everything you need. Open each box
and verify the contents against the packing list. Once you're sure everything is
present and accounted for, it's time to get started.
PreparingtheCaseandInstallingDrives
The first step in building any system is always to make sure that the power
supply is set to the correct input voltage. Some power supplies, including the
Antec EarthWatts 380, set themselves automatically. Others must be set man-
ually using a slide switch to select the proper input voltage. Bundled power
supplies are nearly always set properly by default, if applicable, but there are
rare exceptions, so it's always a good idea to verify the input voltage setting
before you proceed.
Avoid Fireworks
If you connect a power supply set for 230V to a 115V receptacle, no harm is done.
The PC components will receive only half the voltage they require, and the system
won't boot. But if you connect a power supply set for 115V to a 230V receptacle, the
PC components will receive twice the voltage they're designed to use. If you plug in
the system, that overvoltage will destroy it instantly in clouds of smoke and showers
of sparks.
