The HP ProDesk 400 G6 SFF ships with Wi-Fi 6 ready to go

The ProDesk 400 G6 SFF typically comes with an Intel AX200 or AX201 Wi-Fi 6 module already installed in its M.2 2230 slot, plus the internal antenna wiring is already routed through the chassis. That means you’re on Wi-Fi 6 out of the box with no fiddling — a nice touch for a business desktop at this price tier.
