This is a great tip. The only thing you have to watch is enterprise grade networking is usually louder and uses more power. You can replace fans to make it quieter on some equipment, but sometimes it needs the airflow. I just got a brocade icx6450-48p network switch delivered for $85, 48 poe ports and 4 sfp+ ports. You can get some great used enterprise hardware for amazing prices.
*arr can also use lists that people make. I have also seen where users can request it in Plex, and *arr will add it.
