Well, here's my entertainment center setup.

I have the Sensor Bar on top of the TV. The Wii is on a shelf below the TV (and yep, that's a Dreamcast on the other side) along with various electronics placed in the TV stand. So I'm not sure where I'd put the Wii Speak device. I guess I'd have to see it in person, the size and how I could place it somewhere.
I'll come up with something better eventually...
