I'm doing some spring cleaning and getting rid of a couple of old computers....first time doing so. I hate getting rid of old things that work perfectly good, but no longer doing me any good and just taking up precious storage space. I have a Dell Dimension 4400 desktop and an IBM Thinkpad Type 2662.
Does a website exist that I can post these for someone who might have a use for them?
