Well the issue with building one, is purely an issue of lacking knowledge. So with enough reading and research (there's videos too)
you can find out how to build a computer. It's like legos people say and that's true pretty much. A more advanced form of legos.
The way to handle parts, is to simply be calm and do things slowly, while only touching the sides of them. Then it's only a matter
of inserting them so they fit. The problem with pre-built, or OEM, is that an extra layer of price is tacked on. You don't get to decide
what goes into the computer, thus it can turn out to be a bad deal for you. However, when you order parts online, there's plenty
sites which also enable you to make them put it all together for you too. If you use a site like www.pcpartpicker.com you're able to
pick your parts yourself and then have someone else put them together for you for example. For 1200$ you can get a very decent
gaming setup I tell you. You're welcome to buy a laptop, but I really recommend only doing so, if mobility is extremely important to you.
Because laptops for gaming cost a boatload of cash, compared to what you're getting. There's also the chance of paying just for the brand.
An example of this could be Alienware. Sure some of the laptops they make are powerful, but damn, they're costly too and it can't all be
because of the parts; thus is must be the brand.
For 1400$ this is something you could get:

Everything is included. Full HD screen, mid-range GPU, mouse, keyboard, SSD etc. It's not flawless and it's not perfect, but it's
at least a starting point. If that's not enough, here's a video that'll show you how you typically put together a computer
yourself, once you have the parts:
