A $339 Beelink N150 vs the yearly cost of a used 1U
A small new mini PC often costs less over a year of power than a loud used server. Skip the used 1U if heat and noise matter. This note is only about the power bill, not which chip wins.
The chip shootout already lives in N100 vs N150. Don't use this page to pick cores. Use it to talk yourself out of a used 1U.
Beelink Mini S13, Intel N150, Amazon B09DPV3D4N snap $339 (12 GB LPDDR5 / 500 GB, 2.5G LAN). Maker copy: “less than 1 kWh/day.” Existing Labthrift n100 guide: wall power high-single to mid-teens watts. Third-party N150-class idle commonly ~6–12 W (PromptQuorum ~6 W; minipcdeals ~8–10 W). Small fan. I haven't metered one.
Official Beelink EQ14: $375 / $429 on bee-link.com. Official available LAN is dual 1000 Mbps. Amazon third-party titles claim dual 2.5G, don't repeat that as fact. PromptQuorum Jul 2026 street ~$189–199 was a different snapshot and is volatile; minipclab.com Jul 2026 says some old Amazon targets no longer resolve to EQ14. Confirm the NIC on the unit. The listing trap is already written in EQ14 dual LAN.
Used 1U named only as the skip: R630 ~70 W idle typical (Hardwarehoard); R720/R730 80–120 W idle (TechFuel 2026 table). At $0.15/kWh, 70 W is about $92/year; 150 W is about $197/year: the same heater math as used vs new. A mid-teens-watt N150 is tens of dollars a year. I didn't invent a used street price.

Skip
Skip the used Dell R630 / R640 as a first lab host. Skip copying Amazon “EQ14 dual 2.5G” titles, official is dual 1G. Skip this page if you are shopping N100 vs N150 chips; that is the other guide. Shape: pizza box. PSU: brick vs 208 V.
