Depending on what you want to use the computer for, you may
want to look for a system with some of these extras (or even
add them to a system if they don't come with it by default):
-
Sound card: Some systems come with built-in sound
on the motherboard; others come with a sound card that
plugs into the motherboard. Built-in sound is cheaper,
but a separate sound card offers more flexibility for
later upgrading.
-
Speakers: These plug into the sound card, so you
can hear the sound. Unless you listen to a lot of music
through your PC, or want ultra-realistic sound in games,
cheap speakers should be fine. If you buy speakers separately
from your PC, make sure you buy the kind designed specifically
for PCs, because they typically have better magnetic shielding
than regular stereo speakers.
-
Internet access: Many PC makers want to sell you
a year or so of Internet access, or even discount your
PC if you buy it. If you can get a hefty discount on your
PC and you don't already have an Internet account, it
may be worth it. But beware of signing up for more than
a one-year commitment, because Internet technology is
advancing quickly. Two years from now, everyone but you
may be using some newer, faster Internet connection technology.
-
Ergonomic Keyboard: For a few pounds more, you
might be able to replace the standard keyboard with a
fancier one with a special design for preventing wrist
strain.
-
Optical Mouse: For still a few more pounds, you
might be able to choose a mouse that doesn't have a ball,
and therefore doesn't get all dirty and gummed up.
-
Modem: If you need a modem to connect to the Internet,
you might be able to get one pre-installed in your PC.
Even if you have cable or DSL or some other Internet connection,
you may wish to get a modem for faxing.
