I'm happy to answer any questions around this! We've been working on this since update since we launched the product last year, so we're excited to be able to share it today.
Any chance of 15”-16” in near future?
I wondered this too, but they will need a way to be able to plug the same Mainboard into a new chassis such that the Expansion Cards work correctly, or else design a new Mainboard with increased size (or I guess longer Expansion Cards, but that seems silly).
