Creator here!

I did consider Euro Rack, 19" racks, MiniATX and other case standards. But with any of these options, i wouldnt be able to keep the price low. The case including all parts and assembly cost is roughly at 20€ per device. It's an off-the-shelf part, with only lasercutted parts in two materials, and a single custom component which is yet to be determined what's the cheapest manufacturing option.

I wanted to keep the price low and any of the options above would increase the price by at least 40€, which is a subatantial part of the components

It looks like it could be future-compatible with a possible Euro Rack refit? Nothing cooler than DIYing a DSP for your DIY modsynth!

Heightwise, it fits: 100mm vs ER's ~128mm; trickier with depth - 180mm vs "deep" ER modules ~100mm. One option would be a rack with no back panel. Power in ER is already being distributed via a ribbon cable so this shouldn't impact the ability to install standard modules. Electrically - 12V, perfect match.

What is the width of each module? Assuming (250mm-case)/8 ~= 30-32mm?

Module spec should be around 85x28x100 mm size, so we'd have a deep module with around 15mm of "front extrusion" to fit the modules.

It's definitly possible to re-layout the backplane into a different mechanical design, and reduce the number of slots

Final specs will be shared soon, i have to do another revision of the hardware design as i figured mechanical properties like that the "stickyness" of PCIe slots is good enough so you dont actually need mechanical screws to fasten the modules
