We wanted to use a old raspberryPi and a bananaPi, and first problem to overcome was the enclosure.
So a laser cutted enclosure was the answer, as the 3d printed one took too much time to print.
Every eletronic parts are screwed to the side and back panels. Those panels can be cutted again to add or modify system resources.
The white enclosure is used as a bench power suply. The brown one is waiting for some parts.
