Someone did an oopsies there.  Not only did they try to reflow the solder but looks like the components flowed to the table.  :-DD

Even the hinge fell off. That board is unhinged.

I lost mine years ago. |O
It is only when a mosquito lands on your testicles that you realize there is a way to solve problems without violence.

Looks like most of the other BGAs and SMDs stayed, but the main GPU along with a bunch of TH parts came off. I'd expect TH parts to be less likely to drop off, but I guess there's a size/weight/pins ratio difference?

Yes indeed. It's fairly common practice to put PCBs through reflow a second time with lower-weight components flipped to the bottom while soldering the top-mounted components. Works fine for light components like decoupling capacitors (hence why you will often see boards with only light-weight components on the back).
