Unless i am getting it wrong but i think it's about the fact if there is any interest or not ?
Looking at this it almost seems like a group buy for boards already :grin:
Oh yeah before i forget i am interested in this project :thumb:
What size are the small boards? I know that you said that they would fit into a 500 series rack (3u), these can take boards up to 135mm high by 145mm deep (maybe a few mm out, dont have the specs here).
Seems like the big board might fit onto a small board?
