“But computers are so cheap these days,” you say. “Why waste the time and energy building your own system when you can get a great machine fully assembled and shipped to your door?” That’s a great question. Building your own PC will not save you time. It might save you money, but that’s not even the best reason to do it. For me, it was a fantastic hands-on educational experience. It gives me a deep sense of satisfaction every single day when I press the power button on my tower, watch it light up, and know that I plugged in the wire that goes from that light to the motherboard.

There are other good reasons to build instead of buy, too. With your own build you can customize your system just how you like and make your perfect media center or gaming machine. You can save money if you already have some parts (though see my warnings on the dangers of a “Frankenbuild” below). Upgrading your PC in the future becomes easier and cheaper since your parts aren’t tied to a particular manufacturer.
