I have a gaming laptop at the center of everything. From there I have a plex server that goes to chromecasts around the house. I also use netflix, amazon prime, youtube, and Google Movies (when I have the survey credits). I also use hulu on and off depending on if there's something I want to watch. I also have a shield tablet which I can use to play games around the house or hook it up to the downstairs TV to stream. If there are sports matches I want to watch I generally go to a bar. I didn't like that last part at first but there's a consistent crowd that's really into it and has some shared hobbies, so it ended up being better than I thought it would be.
The other thing I did was get a coax card for my PC. I installed a nice antenna in my attic and can record the signal that comes in. It's hit or miss but we get some sports, some news, some basic cable shows. All without tying up bandwidth.
