Desktop PC Computer (Walton on the Hill L4)

Thanks for viewing my post.
I wonder if anyone has an old computer that they are no longer using. I don't need one for myself but like to refurbish old ones which I can then give away on Freegle as a working machine.
I have given away at least 5 computers or laptops so far. If you can help me to help others, it would be appreciated.
Thanks
