But fair feedback, noted. I can't move the optional OCXO below the enclosure, as that would be taller than the aluminium block itself and require a slot breaking the RF shielding, but maybe I can move the connectors. I'll try and get creative.
Edit, surface-mount MMCX to the rescue? https://i.imgur.com/1GJhJa6.png
I can't stand the amount of fragile connectors people keep installing on expensive boards. My BladeRF's micro USB 3.0 sheared off.
USB-C is even a bit contentious for me. USB-A with the 3.0 extensions is much more durable.
Best of luck with the project. I couldn't find anything on "Granita". Is it called "SnowWings" now?
The Granita is technically unreleased, the manufacturer has been making changes to the packaging of the chip as recently as a couple of months ago. It's based on the same silicon as the IceWings: https://arcticsemiconductor.com/icewings/
The idea is however you get shielding and cooling, sit it on the desk upside down and have all the RFNM boards accessible from the top.
