Hi Benjamin
If you boot holding down ALT on the keyboard you'll see a list of all the boot
drives available to the Mac. If the Mac scans the firewire port and sees the
IcyBox enclosure it'll ask it for any drives connected. If for some reason the
IcyBox enclosure's controller chip doesn't respond in the correct way or
doesn't understand the boot requests, then the Mac won't find the RAID0 (or any
other boot volume) to boot from.
The Western Digital Studio Passport was a mobile FireWire800 drive marketed for
use with Macs, the only problem was that it wasn't bootable due to the chipset
and firmware on the drive controller card, making it entirely useless for me.
It's unlikely given the generic, adaptable nature of the IcyBox enclosure that
it wouldn't support booting, but installing OS X on a single drive connected to
the IcyBox then booting from it will test the 'bootability' (if that's a word)
of the enclosure.
If you are able to boot the RAID, the fact that it's a software RAID will slow
things down, also that it's on the FireWire800 bus will greatly hamper the
speed of the drives, you might find the system to be very slow and show the
spinning beachball much more than normal.
Don't suppose your Mac's got a thunderbolt port? If it's the 27" 2011 iMac then
you can also fit an additional internal SSD drive to boot from, then store your
data on the mirrored RAID, will be like a new Mac.
