Nerdifying My Classroom (Computer Take Apart)

Last year, my students were able to take apart old computers from our school. It was a great learning experience. Each student had a role in their group, which made the daunting task of taking apart the computer, and later putting it all back together, a fun learning experience.

This year, I would still like to have the students take apart the computers and put them back together. However, I would like to be able to use the computer parts for other STEM/STEAM activities. The computers are old Dell computers, but I believe that they have to still be useful in some way.

If anyone has any suggestions or links of how to reuse the computer parts please let me know.
