That's a big rack for a living room, no matter how pretty!
I bought one of the Peerless 32U fully assembled racks for my A/V closet. It's not fully contained (no side panels or door). If you go down the Omni path or one like it, just watch the shipping cost - these usually have to come truck freight, which can make it a non-deal!
I chose this one as it was cheaper than the Omni and other options, and was going to be in a closet anyway. I specifically wanted a rack with carpet-capable casters... With the inclusion of the 5 shelves, it was the cheapest of any answer I could find.
Middle Atlantic also has a "Residential Design" series rack that you might want to look at if it'll be out in the open. But it won't be 42-44U tall (35U max, I think).
They have options for side/rear panels, too. (I don't think there's a door option)
If you're thinking about the custom faceplates, I don't think you want to pay for a door. That's a lot of money to hide behind smoked glass that you'll never see. If you enclose the rack, you won't see light around the components anyway. Also, check to see if your existing components have rack ears available, and if they're truly rack-unit-height. Some components have ears, but aren't exactly a whole "U" high, and therefore leave a gap if installed without a faceplate.
The good news about the custom faceplates is that they'll fit on any rack. The bad news is that you have to replace them when you upgrade components. Keep that in mind. You can easily spend more on faceplates than the cost of a nice AVR.
