Based on nothing but an educated guess, I am going to assume you have never built a computer. I understand lots of people here will try to tell you to do so as it is cool and useful to have the knowledge. But, I would advise against it because when (not if) your computer messes up, you will have to find out how to fix it, and it is a huge hassle. Especially someone not exactly knowledgeable about computer parts.
You can get a nice desktop and later, when you hopefully understand more you will be able to replace the most quickly outdated parts (itt: video card, ram, hard drive).
You could even get a laptop, based on your ability to save up 1000$ without (I'm assuming) a source of income you are well off financially and could replace your computer every once in a while without too much begging involved. In that case, I recommend Toshiba.
I don't want to nay say an opportunity to learn a valuable life skill such as this, but unless you know an adult friend that knows how to do it. I would buy a pre-built computer.
