I am trying to source for PC parts for a hands-on workshop. The goal is for students to learn how to assemble the main components of a PC into a desktop casing. Due to the limited duration of the workshop (60 minutes) I am looking for parts that easily slot into a casing ... very much like a LEGO set. Do you know of a place online I can purchase such a basic set of PC parts. My alternative is to source regular PC parts but I was wondering if there is such a learning set out there for children. Thank you.
