Both share 16GB of memory, but the M2 Pro S's newer platform and larger 1TB drive make it the more future-proof choice, while the SER3's dual-core Ryzen 3 3200U is the slower processor of the two, built for browsing, documents and 4K playback rather than multitasking. The SER3 answers with a lower price and a longer three-year warranty against the M2 Pro S's one year, which matters if support is a priority. Buyers who want more storage and slightly faster memory should choose the GMKtec NucBox M2 Pro S; buyers who value the longer warranty and lower cost, and whose needs are modest, should consider the Beelink SER3.
