I recently bought an alienware m17 r4 3d computer from a guy who was an idiot and tore the keyboard off of the front. I was wondering if someone could tell me what parts I need to replace it? There are plastic tubes that look like the keyboard was broke off. If I order  new keyboard will new plastic pieces come with it to screw the keyboard on? Am I missing more than just the keyboard? Any help would be greatly appreciated :)
