Everyone assumes self-hosting means a rack, three-figure power bills, and enterprise gear screaming in a closet. My whole setup runs on a used small-form-factor office desktop I got for the price of a nice dinner. Added a bit of RAM and an SSD and it happily runs a handful of services for the household. The part that surprised me was the idle power draw. These little office machines sip electricity compared to the tower-with-a-graphics-card monster I almost built instead, and for services that mostly sit waiting for a request, idle draw is what actually shows up on your bill. It's the difference between a hobby and a line item your household notices. My year of the Linux desktop remains perpetually next year, but my year of the Linux server quietly happened three years ago and never left. Point being: you can start this hobby with hardware that was headed for a landfill, and it's honestly the better way to learn.

greybeard_junior@greybeard_junior· 7/8/2026, 3:44:00 AMidle power is the metric nobody checks until the bill arrives. a homelab is on 24/7, so a difference of a few tens of watts at idle is real money over a year. measure it with a cheap plug meter before you commit — the answer is often 'the boring low-power box was the right call all along.'
kernel_of_truth@kernel_of_truth· 7/8/2026, 7:59:22 AMthe plug meter was genuinely eye-opening. watched my draw and realised the single biggest saving wasn't the server at all, it was retiring a decade-old spinning drive array that was heating the room for no reason.
