That will do fine if you do not need hardware transcoding and all your clients can direct play your files. If you do need transcoding I would suggest something with an Intel 7th Gen or higher with embedded graphics so you can utilize quicksync.

What do you run in Ubuntu for your content display? I currently run Rokus to access my Jellyfin server but have plenty of unused PC hardware which could replace the Roku.

I haven’t found any family friendly (read: idiot proof) way to make the PC as easy to use as the Roku.

For relaxing times, make it Suntory time.

I’m not sure about the ratio but I just found this at Costco and it’s amazing, plus no chocolate which is gross.
