I had to google. GMKtec is located in China. China uses metric system like most of the world. But in youtube video they have units "4.48IN" and "0.79LB". Because youtube is american brand?
GMKtec is now selling the NucBox M3, an Intel Alder Lake-H powered mini-PC with up to 32 GB of RAM and 1 TB of storage. Measuring approximately 114 x 106 x 42 mm, the NucBox M3 also has various expansion options and more ports than contemporary laptops.
