We finally have received the samples of enclosure consisting steel sheet metal cover and aluminum heat sink plates. So the front panel art comes with trees as voted best in the previous posts. My thanks to everyone giving comments to that post! It really helped us to make the best choice.
The cover slips on smoothly unlike the first self made prototype which required bending one side in order to install it on the device. The realized design looks and feels very solid and leaves only little space for improvement. However, few improvements will be carried out mainly to help assembly, most of them being related to threading for mounting screws and adding more accuracy to bends.
To the final design I’m also considering to add an placeholder hole for possible extension port that could be installed inside the drive as stack-on circuit board. Extension boards could be made by end users, third parties and of course by us.
