Any computer experts?

I'm am completely naive when it comes to anything more than performing media tasks on a computer, I'm hoping maybe a few of you have more expertise in this area.

I'm interested in getting back into World Of Warcraft to play with some friends and co-workers. The computer I have now won't run it, plus this laptop belongs to my wife and she doesn't want my WoW time cutting into her FB time.

I'm interested in building my own machine because I hear it can be done relatively easier and far cheaper with better specs compared to a store bought system.

I jumped on Newegg and went to looking at things like video cards, motherboards, and processors. The problem is, it all might as well be written in Mandorin Chinese.

Does anyone have a link to a guide that can explain some basics to me, or another forum with a newbie section so I can start reading up?

Thanks so much.
