Can i upgrade an HP Omni 200 quad series ?

Hey there, Im looking to buy a computer for gaming and and other stuff. im on a "under 1000 dollars budget" so an alien ware is out of my reach. anyway I found this all-in-one pc and because its slim and doesn't have a huge clunky tower, i could travel with it. But one thing is i can't play games with it's installed graphics card, and i can't customize it at a store and i don't want to order one. So could i upgrade the video card/graphics crad if i wanted to.
