If you need 4k you’re going to need a shit ton of storage. If you go for the good quality profile 4ks you’re looking at 50GB easily per file.

Sonarr and Radarr can fetch downloads, yes. You’ll need to configure your indexers and then you’ll need to set up your download clients. I use a torrent server and sabnzbd.

You’ll need a graphics card that can handle transcoding 4k I’m not sure which is best. Ram and CPU won’t be the biggest concerns for you.

You’ll want to do some research on nzb files and their transfer mechanism. I’d say both nzb and torrents together is the best option because you have redundancy rather than one is better than the other

It’ll be harder for sure but mold like cool damp places to grow so anytime you have such an environment you’ll be fighting that battle.

Definitely a good counter measure to help limit it but I’d estimate you’ll likely add a day or two before you need to clean up.

There’s some concern about cleaning the sponge/absorbance medium as that’s a fantastic area for mold growth.

Not a barrier but something for consideration

Sauce plox.
