Good investment. Would recommend you set up raid 1 for the hard drives if you can afford it, single redundancy is very nice to have. I'd also recommend jellyfin over plex or any of the other big proprietary players out there. Jellyfin just works, and has a pretty good list of plugins for metadata.
The biggest drawback I've found is that I did have to make an account with opensubtitles to have automatic subtitles, and if you try to load too many pieces of media at once you may run into the 50 api's downloads per day limit for free accounts.
