Summary

Here is my version of the BC-250 case.
It is designed for the BC-250 motherboard and Flex ATX power supply.
The case was created based on the case from @Arthrimus.
The power supply compartment has been modified, it is slightly larger (42.2x83.8 mm) (the walls are thinner to keep the same case size as the original) and there are holes at the bottom to vent air from the power supply.
The front panel is designed for a round button.
I am also adding a bracket for two 120mm fans made by @isaacalvex.
