In Figure 7 you can have an overall look inside Panzerbox. As you can see all internal parts are painted black.
As shown before the slot covers are meshed. Daughter boards are fastened to the case using black thumbscrews, which we think is a better solution than using screwless mechanisms, as they tend to break after a while, especially if they are made of plastic.
You can see the rear and top fans in Figure 9. See how the top panel is meshed. On Panzerbox you can install a water-cooling radiator with two 120 mm fans. In order to do that you need to remove the top 190 mm fan and use the two provided brackets to fasten the radiator to the case top panel.
