Ok, so I've seen people ask this a bunch and I know its been posted before. But, I decided to add a little more info. I added a spot where you can buy EU Keys and you can also buy US Keys there too. Now, onto the guide!
Hello all !
Firstly, you must have an EU account to play.
This can be done by purchasing an EU CD Key with EU Burning Crusade CD Keys.
A list of sites (will be updated) here tells you some websites to buy from:
Buy WOW Gold, MMO Currency, Power Leveling, Gamepoints | | OffGamers
Buy World of Warcraft Gold. Cheap WOW Gold. | CD Key / Game Points | OffGamers
Game Codes, Game Time, Registration Code Keys, World of Warcraft, EVE, DDO, Lineage 2, Ultima Online
World of Warcraft WoW Gametime and Account Registration Codes

Once you have your account set up, the next bit is even MORE simple!
Find your main World of Warcraft folder. Usually, if you haven't changed it, it's c:/program files/World of Warcraft - Go to that folder, and find a file called Realmlist.WTF - You must right click this and open it with notepad.
You will see 2 lines, with US in them. Simply change each US to EU and save the file. Then open up World of Warcraft, and log in!
Just trying to help people who have this question. If anyone has any question or comments please let me know! You can also PM me!
