I would like to add and SBC to my Windows 7/10 network that would hold all of our music and movies/TV shows. It would need to be fast enough to allow 3 devices to watch a movie at the same time on the home network and possibly stream a movie to a device outside the home network. I would also like to setup network level ad blocking (Pi-hole) on this SBC. I would like to install the OS on the external HD (2-4 TB) with the music and movies. I have 200 Gig internet service and TP-Link AC1200 5G routers. I'll put the SBC in a case and put it on my networking board/rack in the basement. Please give me recommendations for an inexpensive SBC and operating system that would allow me to accomplish all this. Thank you!
