Mostly dell optiplex desktops with ddr3 from the windows 7 era. Or whatever neat looking device i could find.

How do i find a charity/place who will take them?

I have a mix of eras of computer ranging from ddr to ddr3. most of what i have is from the windows 7 era, my “collection” mostly contains dell OptiPlex’s or whatever looks neat.

Ive heard you can do alot with a dell OptiPlex but i want to make a nas but im unsure how well it would be to store personal files with?
