He should recycle them. These machines are usually pawned off on seniors in very shady "deal of the century" sales schticks. My 72 year old father in law bought a complete pos laptop for $200 that was an abandoned machine from a repair shop. It didn't have any drivers installed, it was running Vista and it could not connect to the internet.
Rossman may not be selling under such shady circumstances, but this is how most of these machines are moved. I don't think any good comes out of selling these machines.
