I can see the "Framework motherboard as SBC" idea catch on for everything from set-top boxes (Steam Machines could make a comeback this way) to a poor man's blade server.
I’ve tried a few times in the last year and finding parts (that are actually available) for a sub- $500 small-form-factor system seems to be beyond my capabilities :)

Or could one fully use it "standalone" providing they supply their own usb-c power, memory, storage + external keyboard+monitor?
edit - looks like it can. the 3d printable case is slick, wish it was sold in the store: https://frame.work/blog/mainboard-availability-and-open-sour...
Best of luck with that. I know with UPS even the Ground services include the possibility of going via air if the destination is even slightly disconnected from the US mainland (and I distinctly recall having to program ERP/WMS logic for blocking ORM-D shipments entirely to the Catalina Islands' zip code because UPS would accept the ORM-D-marked package, try to load it on a plane for that last hop, and then send us nastygrams about us being the ones somehow at fault for it); I don't think FedEx is any different in that regard.
It's definitely possible to ship batteries via air, but it has to be marked air cargo only and the fees are probably too steep to be worthwhile unless you're shipping a bunch at a time.
