First of all, please check out my WTB request for a Xenarc 700TSV front panel:
WTB: Front bezel/panel/frame/case for NEW USB 7" XENARC
Good money for your front panel if you are no longer using it.

Here's the question:
What are the physical differences between the 700TSV-RS232 and the 700TSV-USB?
The RS232 version has blue buttons, and the USB version has black buttons.
Anything else?
Would the guts from the USB version fit in the RS232 case, and vice-versa?
Thanks!
