Holy sh!t. That looks pretty bad. As GottiBoi55 has mentioned, you have accidental damage COVERED for one year. Possibly 2 depending on your purchase perks on certain cards.
Send it for an RMA, or order in a new panel to fit yourself. You have mentioned you are not familiar with computers, so RMA'ing may be your best bet.
PX will not assist you I believe, you need to call Asus Service Center directly.
YOU PAY FOR POSTAGE ONE WAY. Asus will cover the cost of sending it back to you.
