This is a case for the Asrock BC250 that is being transformed by communities into a "Steam Machine" for Linux gaming.

My build needed to incorporate the BC250 board, the flex ATX PSU, a 20mm front switch, and 4 Arctic P12 fans (2 each side of the case).

I have printed this all on the A1 - of which the build plate wasn't quite big enough to fit the full case in one go. 

There was a need to combine the two halves together with two fan-screws and M3 brass inserts.

I have added all my working files so you can amend however you need.
