GMKtec NucBox G3
GMKtec NucBox G3 is aimed at browser-based work, media playback and lightweight home services. Its Intel N100 and integrated Intel UHD Graphics suit modest workloads; larger builds, demanding games and heavy rendering need more headroom. Replaceable SO-DIMM memory gives it a path for later RAM upgrades.
