In Figure 5, you see the top panel of the case, which is plain, with no openings.
In Figure 6 you can check the small panel containing two USB ports, earphones and microphone jacks, and the reset button.
The bottom panel of the case has a mesh where you can install an 80 mm fan (not included).
The rear panel of the R-2 Toast is a quite conventional for a mid-tower case. The power supply is installed at the top, the case has seven expansion slots, a mesh above the slots, and there is room for two 80 mm fans, but the case comes only with one of them installed (it doesn’t support speed monitoring and the manufacturer doesn’t publish any technical information about this fan). As briefly mentioned before, the right panel (shown on the left in Figure 8) is not removable, but the left panel is secured by two silver thumbscrews. The rear panel and the interior of this case are not painted.
