These are a bunch of computer parts from computers I’ve taken apart over the last year. I like to tinker and take old stuff I get apart. I do not know much about computers, but these all should work, but I can’t confirm as I haven’t tested any or know how to. All come from Dell/HP desktop tower computers used in a local office. Some from laptops, and other telecommunication computers. Price is negotiable, DM with any questions. Thank you!
