Wow, it looks like it was launched from a catapult, that thing really came apart.
Funny, it's air travel / aircraft related, as the one other time I saw a MB (in this case a much older MBP) get that decimated, a biz partner of mine was working on a presentation waiting for the plane, it wound up being a walk-across-the-runway smaller aircraft. He gets up to the top of the entry stairs and kind of spins around to see where I'm at, and loses his grip, the MBP launched, and while it was really beat up, case dinged, kind of separated a bit (like yours), cracked display, it actually
still worked!
I guess if it were me, and I was getting a replacement __and__ they didn't want the carcass back, I'd try to get it running, external display and KB, maybe transplant it into some kind of generic PeeCee case[?] I mean, I'm sort of a tinkerer, so I'd do it just for fun (or "fun", depending on your perspective
)
