I think you mean an Intel CPU for transcoding. Pretty much every piece of software can use QuickSync for hwaccel. My Celeron NAS can handle 3 simultaneous Plex transcodes as well as a 5-camera Frigate setup without breaking a sweat.
To OP - if you want energy efficiency AND ML, you will want pre-baked models that can be used on an edge compute device like Google Coral.
Would love some more photos. I’m likely going to build similar specs in that case when the 50xx range release.
