At one point I built a "Steam Box" that ran Windows (because, at the time anyway, lots of things didn't run on Linux), and hooked it up to the TV. The only problem I ran into was that lots of games don't do controllers well, either.

I have the same setup and controllers aren't really issue on modern games anymore - they're all released for consoles as well so they usually feature good controller support.

I did the same thing. It ended up being used mostly for watching streaming services instead of gaming for social reasons (the TV is in a shared area). I ended up buying an even bigger more powerful gaming PC with dedicated gaming keyboard and mouse and no controller. Linux for work, Windows for streaming TV, Windows for gaming.
