Looking for preferably FOSS programs to torrent, categorize, and play content.

I used Plex on a FreeNas server before and honestly hated the overall design. In the end, we ended up nuking several hard-drives by mistake.

We’re starting over, and pretty new to the current scene. We’re shooting for a Raid1 setup, and preferably an end GUI that has the ability to add movies/shows to a grab-list (free/paid options would be valid).

We have a seedbox 5$/month, several private trackers, and the following hardware:

Currently have 2 8TBs, several old computers, 6+ RX 580’s from an old rig, 2-3 CPUs, and maybe an average of 8gb on each of 4 motherboards.

What is the coolest setup possible ;)?
