There are about 3 parts to this area. The LCD lid (most makers replace the entire lid because they need to avoid time on the expensive tech bench), the cables, connections and motherboard.

Given what a new machine with twice the RAM and what looks to be on par with most X55A's I'd look at http://www.amazon.com/Best-Sellers-Computers-Accessories-Laptop/zgbs/pc/565108 in the #1 or 2 slot and sell this off as-is.
