I'm still in the planning stages since the trailer is winter-bound until next April. I don't mind buying parts now, mind you. Additional info: SFF obviously is welcomed, and both 12V / 120V power is available.
Yeah, I found those tv tuners, just like the Hauppage would work. My main concern is radio, alongside powering the speakers.
edit: woah, I just read the specs of the Aver link - FM radio - that's great!
