Probably not the most cost effective way of getting components for projects

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

Even the hinge fell off. That board is unhinged.

I lost mine years ago.

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).
