In 2010 I built a small HTPC[1] in an Antec ISK300-150[2]. Started out with 500GB HDD + 8GB RAM, then replaced with 2TB SSD, then added another 4TB SSD and another 8GB of RAM recently. Started out TV-connected, but for years now it's been running Ubuntu headlessly in my basement, hosting containers, automations, TimeMachines, etc. Not sure if you'd call it a homelab. Wonder what do people do with their multi-PC racks that can't be done with one small machine like this? (besides running LLMs of course)
