David,
Linux is pretty tolerant of hardware changes (unlike certain other
operating systems which refuse to even boot up, and then require
"re-activation"). Perhaps if it's not too expensive you might keep a
spare video card, as this appears to be on the most fiddle-prone areas
of building a myth system.
If the IDE/SATA interafcae of your new motherboard is not exotic it
should boot straight up.
Cheers
Steve
