Quiet Homelab: OpenShift Cluster on Refurbished ThinkCentre Tinys

This post details a low-power, quiet homelab built using refurbished Lenovo ThinkCentre Tiny PCs. Running Red Hat Enterprise Linux, these compact machines are used to host an OpenShift cluster, though they're versatile enough for Kubernetes or other containerized applications. The author details the hardware, costs (around €416 total), and even provides a 3D-printed rack-mounting solution. A perfect example of how to build a powerful yet unobtrusive home server setup.
