same here. I have 12+ demopods but still missing some european editions (like the Gamecube one being listed).
12+
cool!!! 
any chance you could post some pics of those beasts?
In this forum? ;-)
I have
SEGA Mega Drive
SEGA Master System (don't know exactly - it just says SEGA) (3x)
SEGA Dreamcast (2x)
SEGA Dreamcast w/keyboard Add-On (Surf and Play)
SEGA Saturn
NINTENDO Gamecube (german) (2x)
NINTENDO Gameboy (german)
NINTENDO Gameboy Advance (2x)
NINTENDO Gameboy DS (german)
NINTENDO SNES
NINTENDO N64 (2x)
SONY Playstation I (german) (2x)
SONY Playstation I (EU Edition)
SONY Playstation II German Edition (3x)
SONY Playstation II European Edition (w/Eye Toy Add On)
SONY PSP
Microsoft XBOX (2x)
Still looking for another Version of the Mega Drive (with SONIC on the Front), and Dutch editions of all other consoles. For european market the demo pods ( or Kiosk Display they are often called ) these are mostly "cooler".
A NES would be fine, too.
Now on my 8 week vacation I'm trying to rebuild the Atari VCS Kiosk Display and a Colecovision and Videopac/Odyssey display.
I was always thinking of rebuilding the stuff from a munich based console shop in the 80s. They had cool furniture on their own (pics later).
You can easily find pictures while just using the google picture search for "display kiosk" or "demo pod" :-)
Some pics are on my website, too:
