Several people asked for more detail on my office and the conduit i ran under the floor. here are some pictures.
in case you did not see the earlier post i was using 2 dualhead computers on a KVM switch. I have recently switched to widescreen monitors but i decided that having 2 widescreens side by side was just too short and wide so i have now rotated them on end. it seems weird at first but i really like it. most things (web pages, word docs, etc) are tall and skinny.
i installed a second graphics card in each PC to drive the other displays in the office. you can see that i have a 720P display above the other displays which is routed to the 37" tv on the far wall. to play a video on it for instance i just drag it up off the top of my desktop display and maximize it. I am about to reconnect my matrix switcher which allows me to route any of the four vga's from my desktops (2 machines with 2 outputs each), laptop or videoconference to any screen in the room.
Below is a little flow diagram of the core av stuff. Basically each pc has 2 dvi outs to a kvm which drives the desktop monitors and 2 vga's that go into the video switcher which drives the projectors and the tv on the wall.
i finally bought furniture for the far end of the office. The brown chair is actually a recliner which gets a lot of use. My office is on the main floor close to the kitchen so I would say it gets as much family time as the family room. It is not unusual to have my wife and kids on the couch and me at my desk when we are hanging around talking.
i have finished the desk legs but they need poly on them. i used strips of 1/4" cherry to make it look like they are rails and styles. I mitred the corners and added baseboard to match the rest of the room. I also ran a small 3/4" channel across the underside of the desk which allows me to route wires from the right leg to the left. this way i can have grommets on both ends with wires coming up. on the left side i have my polycom mic and the expansion base for my laptop wired in. .
the right leg of the desk opens so that i can get to the wires coming up from the floor. A piece of pvc drain pipe comes up inside the leg. This is run across the floor and comes up inside the credenza behind the desk. That fitting is a T and the pvc also continues another 20 feet to come out in an unfinished space downstairs. this way i can get future wires run from the POP downstairs to my office. again, this is just a garden variety drain pipe that i bought at ace.
inside the desk leg you can see the 3" pvc pipe coming up out of the floor.
on the other end of the pipe, the credenza behind the desk has a removable panel as well where the wires come up.
finally, the ceiling has track lights for video conferencing, 2 axiom speakers and 2 projectors. The track lights have a traditional studio lighting layout (key, fill and hair lights).
and finally, here is with the cabinet doors open showing the inside of the credenza. Note that the bottom of the credenza is much deeper than the top so that all my clutter is hidden and the printer is on a pull out shelf.
I will take a few pics of the back of the racks and the access panel that I cut into our coat closet to allow me to walk behind the equipment racks.
