I already posted this before. I'm not sure if this qualifies as a 6th Gen setup per se, but it has all four mainstream consoles in it from that era. The only thing that has changed is a PS3 on top of a PS1 where the PS2 slim is on the left. The PS2 was moved on top of the NES and a SMS and a 2600 are to the right of the Sega Genesis/CD/32X unit.
Also, the diplomas were taken down and replaced with a 39" LED LCD for the PS3.
Very good. I can only disapprove of not using external speakers, you don't need a 2.1 setup like me, just get some stereo ones.
