Here are mine (you can see my whole write up on my process of my "closet" here: http://www.avsforum.com/t/1470115/my-home-theater-rack-and-equipment-room
Here is the back. I have 3 42" tall Leviton Enclorues. They have 4 2" conduits running between them (drilled through the studs; Non load bearing wall)
Here is the front of them (pre-drywall with mud covers on them)
Here you can actually start to see my wiring. I haven't completed this stage yet because for the most part all of my equipment lives in that closet, but I want to have jacks in rooms anyways just in case. The first one here is my network/phone box. The Modem's RG6 cables comes from the middle box over through one of the conduits and if you look closely at the bottom of the 2 boxes, you'll see wires passing through them.
This is my middle box. It will be for some of the A/V distribution (whatever doesn't go into the rack).
The final one I was going to use for whole house audio (just a bunch of speaker jacks) as well as a pass through to the 3 8-gang wall plated (patch panels) below this third one (for getting stuff to the rack like HDMI, Speaker wires, etc).
This is the patch panels I was just talking about
I did a lot more (especially in the power distribution part of my closet) that allows me to keep visible cable mess to a minimum. I'm hoping to free up some time soon to get the actual SMCs wired up properly and get the rest of the runs going. We are expecting a baby in Sept, so I've been preparing for that, which obviously takes precedence (but at the same time, it would be nice to have all this done before then!).
I'd be happy to answer any questions about my setup here, or in my build thread for my closet
