A quiet home lab on a budget
My first home lab was a pair of retired rack servers bought cheaply online. They were powerful, loud enough to hear through a closed door, and expensive to run. After one electricity bill I started over with three rules: silent, under 30 watts at idle, and nothing that needs a rack.
The hardware
- A small fanless mini PC with a low-power mobile CPU, 32 GB of RAM and two SSDs.
- A four-bay USB enclosure for bulk storage, spun down most of the day.
- A cheap UPS that gives everything ten minutes to shut down cleanly.
The software
A plain Linux install with containers for each service, managed with a single compose file per service. No orchestration, no dashboards I do not look at. Configuration lives in a git repository so I can rebuild the box from scratch.
Lessons
Most of what I actually run needs very little power. The expensive part of a home lab is not the hardware, it is the time spent maintaining things you do not need. Fewer services, documented properly, beat many services nobody remembers setting up.
