You'll have to make your own enclosure unfortunately.
That is actually good news, for I am in the process of manufacturing a STX case. It will also include mounting for your Dynamo DC-12V. Also it will have similar layout to the
STX160.0, all of the components will be stacked. It will have an external brick rather than internal like the STX160.0. It will include space for mini-itx cards like the Gigabyte GeForce GTX 1070 0 Mini ITX OC. I will start a thread detailing it further but I am in the process right now 3d-printing the case and test fitting it all.
