Although I admin sometimes it is done very well and in the respect of the casing, like on thie Minitel 5:
Still, seeing photos of the internal brought cold to my spine.
And then 3d print something else, wasting a lot of material...
I don't like it when people have some _working_ unit and they remove the working parts to "modernize" it, but when it's broken - use the parts that remain that are still functional and fit a purpose.
In my mind, arm boards don't "belong" anywhere, as they are small. I've got some modem cases that will be repurposed for arm boards _because they weren't very good modems to begin with_ and their usability as a modem is basically nil... I have modems that _are_ usable and will not be refitted.
This is where I was going with the suggestion... not "oh, a working machine!" but "don't throw it out! repurpose it for something useful!"
