So this is very neat. There's a whole industry that has developed in China where they take old motherboards, chop them up like in the video above, desolder the chips, then make brand new motherboards with the salvaged parts. A lot of time they'll do this to decommissioned high end server gear that's a few generations old. I've bought a number of these boards. It's an interesting option if you want to build a computer on the cheap.
