Building your own computer is a great way to learn more about how computers work. Rather than a mysterious box, you will understand how simple a computer really is. Whether you are a gamer, a student, a casual Web user, or someone in between, you can have a lot of fun creating your own custom computer.

Specifications

Take some time to think about what you want your computer to do. In fact, writing down the specifications you want or need is always a good first step. For example, if there’s a certain game or other program you need to run on the computer, check out the minimum system requirements that are published for the application. That gives you a good place to start by making sure the computer you build will accomplish its purpose.

System requirements usually include CPU speed, memory size (RAM), storage (hard drive or solid state drive), optical drive (CD, DVD, Bluray), graphics adapter, and operating system. Depending on the application, you may also need specific input devices or other software (like DirectX).

Once your list of specifications is written down, you can work on creating a parts list.

Find a supplier

You can’t just go to Wal-Mart to get the parts you need for a computer. You need a place that sells computer parts. While many people will point you to online retailers like New Egg so you can get good prices and selections, you should only go there if you know what’s going on. If this is the first time you build a computer, you may want to go to a local computer parts store. This helps because (1) it saves time on returns and exchanges if you buy the wrong part, (2) you can get helpful advice on what parts you need for your specifications, and (3) if you get in a bind, you can bring your computer over to the store to get someone to help you. You’ll probably pay more than the prices at NewEgg, but the added value will be worth it if you’re just getting started.

Assemble your computer

The assembly process depends on the components you have purchased, but generally, you’ll want to start with the motherboard. Install the CPU and the CPU fan and the memory modules. Open the case and install the power supply, then mount the motherboard inside. If you have a separate graphics card, you’ll install that next followed by any other adapters.

Attach your monitor, keyboard, and mouse and turn the computer on. If you see something on the screen, you’re three-quarters of the way finished. All you’ll have to do is install your operating system (aka Windows) and your other software and you’re ready to work or play.
