Computer Towers

As a general rule:

Your best bet for break down scrap value is something pre. yr 2000.

Your best bet for " better than scrap" is something no more than four years old.

Take CD/DVD boards for instance: The older ones roughly average 1/4 lb each. The newer ones are much smaller ... around 1/10th lb each. The latest towers & desktops generally don't even have a CD/DVD drive because that technology is all but obsolete now.

A pre yr 2000 tower probably has anywhere between one and five finger cards. The newer machines might not have any at all.

An older machine might have 4 full sized sticks of RAM yielding .15 lbs of scrap. A newer machine might only have two sticks of SODIMM yielding .04 lbs scrap.

An older machine might have a hefty power supply that yields copper and aluminum. Some of the newer machines don't even use a power supply anymore. Pull em' apart and they're just a laptop in a big steel box.

Things have changed alot over the years.
