Unraid

A Linux-based OS that turns a PC into flexible network storage plus a Docker and VM host.

Checked against the maker's own documentation on 21 September 2026.

Minimums are what the maker says it takes to boot, not what it takes to be useful. Plan on more of everything. 7.3.2 (2026-07-08) is the latest full stable release; 7.3.3 is currently a release-candidate (7.3.3-rc.1, 2026-09-03) and 7.4.0 is in beta (7.4.0-beta.2, 2026-09-03) as of the check date, so those were not used as 'current'. Unraid's own docs/marketing pages do not publish a specific minimum RAM or minimum disk-space figure (checked docs.unraid.net getting-started and installer pages plus unraid.net product/download pages), recorded as null rather than guessed. base_os left null: Unraid is commonly described elsewhere as Slackware-based, but no vendor page fetched today states this explicitly.
