You could just set up a NAS and a Plex server to do the transcoding for you. In all my years I have personally never had any issues. I have had to struggle with x265 once or twice, and even then I just found a different non x265 torrent and went with that. Not that hard, there are often 10 torrents for a single show, each of varying compressions and qualities.

And I bet that you can find anything you could ever want on nyaa. If an anime/manga exists, it almost certainly is on nyaa, unless it is highly obscure in which case it may not even be there on paid streams.
