What would you do with your own computing cluster? Running a local storage server or a self-hosted website are some very popular choices, but other people would prefer to use the compute power for experimentation. You could, for instance, run offline large language models or a Kubernetes cluster to support your personal projects.

However, the costs associated with building a private computing cluster keep most people from building one at home. As Spencer of the Spencer's Desk YouTube channel recently demonstrated, though, a cluster doesn’t have to be especially expensive. He built a four-node cluster using Raspberry Pi Compute Modules and a mini-ITX motherboard designed for cluster computing. It may not be as powerful as a traditional cluster, but it allows you to experiment with the same basic techniques on a budget.
