2026 verdict
Choosing between these two starts with the operating system, not the spec sheet: the Apple Mac Mini (M4 16GB + 512GB) runs macOS on Apple's own chip and wins this mini PC comparison on owner rating, memory type, and double the memory and storage of the GMKtec NucBox G3S (8GB + 256GB). The M4's 10-core CPU and 10-core GPU handle everyday productivity, photo editing and even some video work well within its size, and Apple backs it with the same one-year warranty as the GMKtec NucBox G3S (8GB + 256GB). What the GMKtec NucBox G3S (8GB + 256GB) offers instead is Windows 11 Pro, a lower price and memory you can actually open up and expand, something the Mac Mini's soldered configuration never allows. Choose the Apple Mac Mini (M4 16GB + 512GB) if macOS and Apple's ecosystem fit the workflow, and choose the GMKtec NucBox G3S (8GB + 256GB) for a cheaper, upgradeable Windows machine instead.
