I purchased a couple switches and a new server for my high school when I was a junior. I also was allowed to buy on the school's line of credit at a local hardware store for things I needed for the stage.

I went to a private catholic high school in a small city. The administration trusted the students. They also didn't have IT staff, so geek speaking technobabble sounds better than paying actual staff. Walked out of high school with independent study classes, real experience in IT and building control systems, and without my parents paying expensive tuition.
