I Build a 10 Inch Mini Rack from Aluminium Extrusions

TacticalCoder

This looks good: I've got three HP NUCs like in TFA + three Pi on my desk (got more than that altogether) and it's indeed a cable mess. > Aluminium extrusions are bars with a groove on all four sides. These bars have a standard format and you can slide all kinds of equipment in there and lock it in place with set screws. It seems to be used a lot for home made 3D printers, CNC machines and whatnot. They're also called "T-slot" and 80/20 (from the brand). https://en.wikipedia.org/wiki/T-slot_structural_framing Plenty of free 3D models for tiny parts for those that can be printed at home (careful though: most won't hold much weight).

Why use the original power bricks, with the space claim and awful routing, instead of just going to a single dc/dc... either directly if no individual power control is needed, or to a relay block or switch block if automated / manual individual control is needed?
