That sounds like a good MorphOS machine. Of course, an ATI card would need to be found. Shipping would be a bear also.
I'm still waiting for the day that my G5 will be on the compatibility list.

I've got a G5 (PowerMac 7,3) Model A1047 here but it has the super huge NVidia graphics card installed and not ATI. It's a Dual 2.7GHz with 5GB of RAM and No HD installed.
I am offering it to anyone who wants to come and pick it up. I am in London, Ontario, Canada. If anyone wants me to ship it to them I could, but it weighs a lot and could be costly.
Please send me a PM if interested.
