Ask HN: Short-depth rack server for home lab recommendation

Hi HN, I’m looking for a short-depth rack server to run small, general-purpose workloads and experimentation. Probably not CPU-intensive. A bunch of Docker containers, some microservices, nginx, a small PostgreSQL instance, etc. It should be short-depth (< 15“) for a wall cabinet and of course run Linux well. Affordable would be great, but not looking for cheap. Any recommendations?
