Nice and clean install.
I just finished my CarPC install in mine a few weeks prior. One suggestion though is paint the front frame piece black so it blends in better with the dash. Anothe option if you wanted a slot load DVD is moving the AC controls down. I plan on getting a 16:9 display so I can do the same. A bit of hacking is required on the support piece but not too much. See my thread below.
Also since you have a S197 additionally you may be interested in replacing the blank with the mycolor switches and cluster. Checkout the following if you don't have the mycolor harness
And finally if you want to replace all the LEDs in your car you can look at the following. The only difference is now if you want blue LEDs you can buy the 2010 window and door lock switches since they are interchangable
