I've never built a computer before
I really want to make a good gaming computer but I'm not really sure what I'm doing
The thing that scares me isn't really picking out parts (but I could still use help with that)
It's more putting the parts together when they get to me
Here are the part I've picked: http://pcpartpicker.com/p/cF9j
I don't know how you would help me build it but I'm really nervous and worried I'll mess it up.
You've come to the right place, it's where I learnt (and still learning) to put them together. There are many tutorials here on how to build a pc. But you'll get to those later. A good place to start is here >> http://www.tomshardware.com/forum/353572-31-build-upgra... Read this link, follow it's instructions. In the meantime, I'll dig up the tutorial links for you. Good luck.
There's no need to be nervous, so long as you take alittle care, especially with handling the components. It's alot of fun and very rewarding to build your own, not to mention that you can build a powerful pc far cheaper than a pre-assembled one.
But here's the tutorials I mentioned. Read them carefully and if you have any questions, feel free to ask. If I can't answer it, one of the gurus surely will have an answer for you.
