A lot of computer enthusiasts don’t like to admit it, but PC manufacturers have the power of buying in bulk that you’ll never have. Even with their markups, you can often get them cheaper than building your own, especially on the lower end of things. If you don’t have a lot of specific needs—that is, if you just need a simple computer for web browsing, Microsoft Office, and other low-powered tasks—you’ll probably get a cheaper system by buying one, and you won’t notice a big difference between it and something you build yourself.
Keep this in mind as well: often, when you buy a pre-built machine, it comes with a copy of Windows (usually $100), a mouse, keyboard, and often even a monitor or speakers. If you build yourself, you’ll have to buy those things separately, and the price can add up fast.
Also, this should go without saying, but just in case: if you need a laptop, buy one. Building a laptop is a whole separate ridiculous can of worms.
