Thickness: Max Thickness 1.06 inch
Build Quality: The build quality is fantastic. The base is metal and quite solid, and the materials used feel premium. The back panel is mainly plastic and flexes easily

Stand: The center-mounted stand is quite heavy but small, so it doesn't take up a lot of space on your table.
