Get someone you know is great at building PCs and get their help! Do not attempt to build a PC for the first time all alone! I cannot stress this enough! I made that mistake and thought I was doing well, and when I skyped my friend who builds computers for fun (I don't understand how it's fun, but I guess some people really enjoy it) and I had to end up taking apart pretty much the whole computer and re-doing it (lucky I didn't plug it in or else that would have been $700 and something completely wasted!). This was after I'd spent pretty much all day doing it.
