Assist Figuring out Xbox

Lifelong Ps proprietor right here, haven't touched an Xbox since Halo 2. Occurred throughout this cleansing out a storage unit. Was gonna attempt to repair it up and take away the let's say paintings (HDMI port is damaged).

My concern is I can't determine what sort of Xbox it’s. I do know it's a One however Microsoft's naming scheme is mindless. Is it X or S or neither, or does it probably not matter?
