Heya HN! We've built a Raspberry PI CM4 based SSD NAS for home hosting. We built it as a part of KubeSail.com - which is a platform aimed at making self-hosting easy and at making the technical bits (tunneling, backups, updates, etc) as easy as possible.
You may have seen plans for this about 9 months ago on HN, but we're finally in full production! I'll be booking tickets to fly out and help assemble the 2nd batch in a few days - we're effectively a two person computer company, which is a lot of fun and a crazy amount of work. Our mission is to make home-hosting a website, an app, or just personal photos a reasonable alternative to SaaS products.
