This is how I generally scrap PC's for gold recovery items and stuff.
Modern pc's can be lower in value but there's still plenty of gold from pins, ic chips, ram and the cpu.

Palladium from MLCC's are lower, probably less silver but still enough to make scrapping computers worth while.

To depopulate boards I use a cheap air hammer attached to an entry level air compressor, it's fast, easy and fun.
