Today we have on hand for review Phanteks' Enthoo PRO M Mid Tower Chassis. This is Phanteks? latest iteration of their popular Enthoo series, which have historically reviewed quite favorably. As others in the Enthoo series, it is constructed of steel, with top and front panels of plastic with a brushed aluminum look. Both side panels are held in place by two thumbscrews per side, and with soft washers under each to reduce potential vibration.
