What are you doing with your clusters?

[shadowhelo]

Last month I took delivery of my Pinebook Pro and have been loving playing with it and tinkering and I have been looking at the clusterboard and wondering what projects/containers etc people have been using them for.

I am studying computer science in university and have been debating on adding one to my rack to get into arm clusters/clusters in general.

Has anyone attempted to fit the cluster board in a 1/2u enclosure?
