Homelab Builds

Practical homelab builds for infrastructure engineers. This is where enterprise skills meet kit you can actually afford. Guides cover mini PC clusters, refurbished Dell and HPE servers, Proxmox hypervisor setups, network segmentation with VLANs, and the power and cooling tradeoffs that matter when you run 24/7 at home. Every build documented here has either sat in a production rack or a real spare bedroom. No theoretical gear lists, no affiliate filler. If you want to learn Kubernetes on a £120 refurbished OptiPlex or run a dozen self-hosted services on a Pi cluster, start here. The homelab is a professional development environment, and this is how we treat it.
