Not sure if I missed the cut off, but I'll give it a go.
Samsung 50" 1080p DLP tv
Samsung 1100 watt 5.1 surround sound
XBox 360 arcade, with the hdd from my last elite (after the third Red ring of death it was cheaper to buy an arcade then another elite)
Wii with a charging station
PS3, not the backward compatible, but fortunately I have a working a launch day PS2 that I can plug in, and a working N64 for some old school Golden Eye!)
and ample seating to play with some friends, or just stretch out and beat my wife in Halo.
I know the wiring is messy, but we moved recently and I haven't had a chance to hide the cable yet.
