Picked up the GMKtec NucBox K9 for my home office. The Intel Ultra 5 125H is snappy, and the Arc graphics handle light gaming fine. Love the three 8K display outputs and dual 2.5GbE LAN. The AI features? Haven't used them much, but nice to have. Runs cool and quiet. Only gripe: no USB4 on the back ports. Solid little machine for the price.
