The 1950 XT is not, even when MorphOS spins the fan down it still is somewhat noticable.
Also, one clarifying item.
Even with a PC based 1900/1950 you can still boot from CD and install the OS. But be warned that Mac OS firmware might require a few reboots to get the PC card to "hook up" and start booting so MorphOS can take over. So still your best bet is the 1900 PPC variant. That is bullet proof and works without issues.
At the end of the day, the A1117 is still not officially supported, but a bunch of us use them as daily drivers and they work great... But you may run into issues with video cards because of this. There is only one video card that works as expected with this system. So keep all that in mind...
To get the PPC Mac to boot from CD first, you need to modify the firmware to boot from CD first and then you don't need the PPC Video card.
