Just wanted to say hi and thank you all for this post. I've been looking for a place like this for quite a while. Call it a place for lateral, post-RPi (as in something like post-modernism, maybe?), energy-efficiency discussion.
Like seemingly a few of you, I've got myself lumbered with a bunch of SBCs as of a few years back and found myself frustrated by, and / or wanting to move beyond, them.
Looks like some of you feel similarly in here: SBCs are great in theory but we've hit some limitations with them that are annoying.
Absolutely love the ingenuity shown in this multi-SBC case. I've been wondering if I could do similar ... 'migrate' from the cable-spider, often case-less, mess that SBCs can be, to a more solid, generic footing that more closely resembles the flexibility of traditional PCs. Instead, I've found myself poking around the interweb wondering if this SBC or that accessory, that is different to the Pi (but may lack software / "community" support), is 'the answer' to a more-functional, less 'educational' and reliable SBC experience.
If I've had one fried RPi SD card experience, I've had one too many! Not to mention how often they seem to simply lock up and need manual power cycling. That's not to say they've not been very valuable in many respects though.
