No, I didn't take a pic of the inside of the case...
The unit is currently in use, I can't take it apart for a bit...
As to proprietary hardware, it's not really proprietary... It's got 40G HD, WLAN, Gb LAN, 1 RS232 port, etc..
You could connect a CM11A to the RS232 port... or, I would recommend a PLM.. (insteon)
If you can hook that to your core, I would suggest that first...
Insteon support is coming along nicely..
Hope that answers your questions...
