It's frustrating because a lot of the student sized projects aren't needed anymore. No one needs a file server because all of their work magically syncs to Google Drive, no one can self host a video game server because every game connects to a central server for matchmaking.
I had students build a Minecraft server years ago but iOS, Chromebook and Android clients can't connect to it, only PC and most of them found that very annoying so I haven't bothered to repeat the project.
