Are the minimum stats of the Alienware Aurora good for playing World of Warcraft?

I'm thinking about purchasing the Alienware Aurora from Dell. You can personalize the computer with basically anything you want. I'm wondering if I buy it for $999 without adding anything will WoW run without lag? What all should I add to the computer to get the best WoW performance. I want it to run without lag with all of my settings turned up. I'm also a big scenery fan in WoW (if that affects anything).|||honestly, you don't need to add anything else to enhance the game quality for no lag. just don't download or install any uneccesary. make sure you install all the WoW in order, original then burning crusade, and then wrath of the lich king. and just so you know, alienware is like the best computer for WoW :p
