This is how I recover parts of a computer case that I can later reuse in my projects and whatever is left I just goes to the recycling barrel You can see in the video that I test the flexibility of one of the parts. If it is to flexible is gone. You wanna keep the parts with the thickest metal otherwise that are hard to work with specially when trying to cut them.
I did not wear my gloves and got a couple of my fingers cut!! computer cases come unfinished out of the press thus making the edges really sharp
