The barrel-style power cord and too many USB Type A connectors make this an albatross.

The barrel jack is the best way to go with a 120 watt device, since it completely avoids people trying to run it off their phone chargers and complaining when it "rebooted for no reason."
As for USB, mouse, keyboard, external 3.5" drive for backups, MFA security key, and a couple front ports to copy files from one flash drive directly to another... I'd say it barely has enough USB A ports, but that's what the USB-C to a hub is for.
People still use lots of USB-A for printers, headsets, controllers, storage, phone charging/data transfer, etc. I have a weird headlamp that uses USB-C for its input, but if I connect it to any of my USB-C chargers/power adapters, it doesn't charge. I have to use a USB-A to USB-C cable to charge it.

Is GMKtec a valid company website? When I try to go there, my security apps flipout and call it a fake website..
