The PiStorm is a very good package giving my Amiga 2500 a lot of CPU power, RTG video and even MicroSD support. The downside is that you cannot reach the SD card and Mini HDMI connector when the machine is closed. I found a 3D project on thingiverse for printing a bracket.
I ordered the extension cables for the Mini HDMI and MicroSD.
Pim (thanks!) made the 3D print for me:
I installed the HDMI cable but I want to wait for the SD extension cable also to fit it and test it in my Amiga 2500.
