I'm really curious to see how well the Steam Box does. And by Steam Box I mean all the hardware that gets put out under that banner, however many computers that may be.

It just doesn't make much sense for the normal PC gaming crowd to buy them. A few will, if they want something small in the living room, but the vast majority of PC gamers have desktops already and wouldn't be satisfied with the limitations of a small system like that, anyway, or would want more bang for their buck.

So the primary audience, is seems, is people who normally would buy a console but wouldn't build a PC. Some of these boxes are going to run Linux, and I can't see many people buying those. How many people will really pay $500 or more for a Windows box in the living room instead of getting an Xbox or PS4?

I guess they don't really need to sell huge numbers, since Valve is doing fine with existing PC owners. But it's gonna be a really interesting market for game stuff over the next couple years.
