2026 verdict

Winner

$289.00

A lower price, a higher owner rating and faster memory tip this entry-level mini PC comparison toward the Beelink Mini S12 (N95 8GB + 480GB) over the GMKtec NucBox G3 Pro (16GB + 512GB), even though the G3 Pro actually ships with more memory and a bigger drive. The Mini S12 runs Intel's four-core N95 processor at a low power draw that owners specifically buy for Proxmox hosts, Home Assistant and security camera recorders left running around the clock, while the G3 Pro's Core i3-10110U and 16GB of memory suit general browsing and office work a bit better. The G3 Pro's edge is capacity, twice the memory and a slightly larger drive, plus a second free M.2 bay that the Mini S12 also has, so both can grow storage over time. Neither machine is fast by the standards of this catalog, and both are aimed at low-cost, low-power roles rather than heavy multitasking. Buyers who want the cheapest always-on server box with a strong owner track record should choose the Beelink Mini S12 (N95 8GB + 480GB), while anyone who wants more memory and storage out of the box for general desktop use should pick the GMKtec NucBox G3 Pro (16GB + 512GB).
