2026 verdict
Windows expandability against Apple efficiency in this mini PC matchup.
GMKtec NucBox M6 Ultra (32GB + 1TB) is the better value of the two, costing less while doubling the memory to 32GB against 16GB and nearly doubling the storage to 1TB against 512GB, on a socketed DDR5 platform that can be upgraded to 128GB later, something the Mac Mini's soldered memory never allows. Apple Mac Mini (M4 16GB + 512GB) answers with a considerably higher owner rating, three Thunderbolt 4 ports against GMKtec's single USB4, an internal power supply so there is no brick on the desk, and macOS rather than Windows 11 Pro. Both carry a one-year warranty. Choose Apple Mac Mini (M4 16GB + 512GB) for Apple's ecosystem, Thunderbolt connectivity and a machine owners rate more highly; choose GMKtec NucBox M6 Ultra (32GB + 1TB) for more memory and storage at a lower price, with room to expand later.
