You have enough damage that the whole case would need replacing, plus the monitor panel. If that hinge is sprung, that would need it also. You're looking at at least $600.00 US dollars for parts. A new one can be bought on Amazon for around $900.00.
If you have to pay a tech to do the labor, you've paid for a new one.
Its up to you. I would just connect an old external monitor and keyboard/mouse and use it like a desktop. Then save my money for a new one when I could.
