This is an update to my old mancave at my old house at this link that shows more of the build process:
http://forum.arcadecontrols.com/index.php?topic=94941.0My space is now referred to as The Modular Man-Cave.
The watching movies setup. The simpit is off camera on the left side of the room.

The triple screen "desk" I made out of pre-made shelf board. It's the closest I could find that matched the simpit. It's on casters so I can just roll it anywhere I want. When I don't want to use my simpit I can just roll it in front of my couch for FPS's and other games!

Using the simpit with my 61" LED 3D DLP TV, like I did before.

Using the simpit with the triple screen desk in front of the TV to make use of the 7.1 sound.

Using the simpit with the desk on the side of the room while the TV can be used to watch a movie.

I haven't had much time to play yet, but I'm loving it so far. NVIDIA surround using one single GTX 670 video card has been working excellent for all racing and flight sim games so far as well as FPS's!
I've put off getting 3 screens before because i didn't want to go the SLI route and I have my own reasons for not going with ATI Eyefinity. (3D being one of them). NVIDIA finally got it right!
With this Modular Man-Cave I get the best of all setups within a low budget!
I have an updated extensive video tour of the setup at my new house!
