Your PCPartPicker link isn't working.
Try to post a different link to your build so that we can all check it out.
Here is the link http://pcpartpicker.com/p/RqBTTW, or you can see it from Kilroy's post. BTW thanks Kilroy. However, i actually made some calculations and i am actually able to afford all. If you have any other suggestions please tell me!
Okay, had a chance to look through it finally.
For school, surfing the web, watching movies, listening to music, you can get away with virtually any PC. If you want to play WoW (as a certainty), you don't need such a behemoth of a video card for it. You can go down to a 1GB DDR5 video card, maybe 2GB tops and run WoW at the highest possible settings without breaking a sweat. Beyond that, you're pretty futureproofed with an i5 4th gen at 3.5GHz and 8gb ram, a good sized SSD...I would downgrade the 970 Superclocked 4GB video card and go with maybe a high rated card that's running 1GB, 2GB max if you want to save some money now...and if you're going to store any sort of personal data, and it ain't movies or music, add in a mechanical HDD (500GB's are usually $50 or less, easy; I recommend WD's Blue or Blacks). If you do that, you can get the build below the $1,000 range and be pretty well established with a good gaming rig.
TL;DR translation: downgrade your video card since you don't need a high end one for WoW (but you will for future games; recommend 1-2GB tops), add in a mechanical HDD for personal data backup...the rest looks pretty solid for a long-term investment.
