Mini PCs, low-power hardware, and small-form-factor homelab builds. Idle wattage, N100/N305 reviews, thin client repurposing, and the cheap, quiet setups that actually run 24/7.
Used HP thin clients are still the cheapest entry into an x86 homelab. Here's what each generation actually idles at, what you can run on them, and the upgrade gotchas worth knowing before you buy.
