+1 to beelink but be careful of sketchy resellers. Their website has a direct link to their actual 1st party Amazon storefront that can be tricky to pin down.

I have a fleet of 5 n100/n150 beelinks running k8s that works perfectly well for a super low power homelab. I also replaced the stock m.2 ssds with patriot low power ones but I don’t think the juice is worth the squeeze on that with current pricing.
