heres mine - Sega Blast City is the main attraction - would love another cab (or 2) but just no room
LCD tv hosts the following consoles (wired up using X-RGB3)
SNES, Genesis, DC, Xbox, Wii, Jaguar, N64, Amiga CD32, Saturn..theres a JTAGed 360 and a retail (for XBL) 360 in there also. Various arcade sticks and such, C64, Atari ST and PS3 is also off camera (i hardly touch it - except when i want to watch blu-rays).
The mounted genesis on the top of the media shelf is my JAMMA genesis for the blast when i have urges to play MUSHA or Tatsujin
