I have a lenovo mini pc that I want to setup as a torrent box. Currently running debian. What's a high level general flow or guide to this? Suggested utilities?

I figure basic sharing through samba but I have no idea where to start with torrent setup. I've just used my main pc for torrents so far on exhentai and such but would like a method to do the same on the minipc. Remote desktop seems sort of redundant for starting and managing them. Perhaps some kind of network share the torrent client watches for .torrent files? Though I'd still be doing all the browsing on my main PC and manually copy the torrent files over.
