The R4's most distinctive visual feature is the brushed Titanium door that covers the entire front. Swing it open and underneath is a solid black plastic grille, with two 5.25" bays at the top. Press each top corner of the grille and it will swing down, exposing the fan bay for easy to clean or replace fans.
The power switch and front ports are located on the top of the case, and consist of the normal ports you'd expect to see on a premium case. Power, reset, headphone, mic, and USB make the cut, but it's notable they give you a total of 4 USB ports (two each of USB 3.0 and 2.0).
The rest of the case is a black finished, high-thickness sheet metal, with various grilles on the sides, top, and rear for additional cooling. It's a rather heavy for an ATX mid-tower case, although the bulk of the weight comes from the front door, and thick, insulated side panels. Remove those, and it's not nearly as weighty. Loaded up with gear makes it LAN party unfriendly, to say the least.
