"No matter whether you're putting together a small home network, or
maintaining a major network in your office, you'll need network cables. If
you decide to make your own Cat 5 cable, you'll save a lot of money in the
long run, as buying rolls of cable, a baggie of RJ-45 connectors, and the
necessary tools will be a lot cheaper and pay for itself in a short period
of time if you have an ongoing need. PC911 shows you how easy it is to make
your own network cables."
