I wish all cases had a 12oz Coca-cola aluminum can next to it for perspective on the size of the case. These 3/4 views are hard to determine how big it might be.
For instance, is it bigger than the SG05? It looks the same, albeit minus the slot for a slimline DVD/CD.
While this may be smaller than a full atx case, it is by no means tiny. 11.5 liters is actually pretty big. Now something < 5 liters would be something worthy of the definition "tiny"
