I need to get a NAS, and this just gave me a whole new rabbit-hole to go down. The other builds on their site e.g. (archive.org link because the WP site is struggling) https://web.archive.org/web/20250505085226/https://jackharve... are also very interesting.
I should probably just hook something up with, say, the old Mac Mini I have lying around, but it's fun to consider the options.
