Free computers for public school teacher (Rancho Cucamonga)

I recently updated both my personal and work computer and I'm offering them for free to a public school teacher who will use them in the classroom for their students.
To be sure these computers are used as I wish them to be, I will ask for proof that you are a public school teacher.
Both computers are in great working order.
One is a Dell PC with Windows 10.
The other is an iMac with OS 10.
13.
6.
You may have either or both if you can assure me they will be used by student.
I'm happy to send full specs if requested.
