Your build will work very well for OMV, Jellyfin, Immich and AdGuard, but it is definitely on the high side for power and complexity. The i5-14500 delivers great Quick Sync performance, yet for a 24-7 server you could comfortably use something far lower like an Intel N-series system or a small N100 or N200 mini PC with PCIe expansion, which would cut energy use dramatically while still handling Jellyfin hardware transcoding, Immich indexing and your Docker stack. Even an i3-14100 or i5-13500 would be more than enough if you want to stay on desktop hardware. Everything else in your setup is well chosen, although the 650 W PSU is larger than needed for a machine that will idle most of the time, and a good 450–550 W Gold unit would be more efficient. The Node 804 plus B760M board and 32 GB RAM give excellent expansion headroom, and your mergerfs plus SnapRAID plan using three 20 TB drives makes sense. In short, the build will perform exactly as intended, but you can save energy and money by going with a lower-power CPU or even a compact N-series mini PC platform without losing the functionality you need.
