Before embarking on building your first computer system, it’s important to make sure that you’ve obtained all of the necessary parts to make a functional home desktop computer. For many, it’s easier to buy a pre-built system but the reward of building your own, plus the cost-savings you’ll endure, is worth the effort.

Must-Haves to Build a Computer

Below is a list of the key components that will be necessary for making a complete system. Some items aren’t mentioned, such as internal cables, because they’re generally included with other parts like the motherboard or hard drive.

Similarly, although peripherals like a mouse, keyboard, and monitor are not listed, it’s important to make sure you have them.

Install Drives, an Operating System, and More

Some devices are not important in the initial build process but can be useful later. Flash drives, external hard drives, and external floppy disk drives are a few examples. You can install them at any time, and even completely remove them forever should you choose to since they don’t represent an essential PC component.

While the above is a focus on the hardware of the desktop PC system, it’s equally important that the computer has an operating system so that you can actually use the new computer. Windows and Linux are a couple of options.

Once you’ve installed the operating system, there are other things you should do before considering your new computer “complete.”
