Hi, some remarks from your unsupport team.
1. Prepare a CD with MorphOS 3.15
- for quick test you can put HD from existing PowerMac G5 AGP machine to PCIe one
- sound is supported
- ide is supported
- sata is supported
- usb is supported
- fans handling is supported
- temperature sensors are supported
- onboard lan is not supported
- pcie Rs232 cards for getting debuglog may work (but i have one and it doesn't)
2. Add some supported Radeon card
- nvidia isn't handled and it won't be
- Original X1900GT mac version should work
- Flashed with MAC bios R500 series should also be handled, Sapphire X1950XT (with boobs) works after being reflashed to Mac OF (it works also with PC bios)
- Mac Bios handling in MorphOS differ a bit for handling card with PC Bios but more or less everything is handled (including fan control both on mac and pc bioses)
- if flashing doesnt work please check with other atiflash version, some version works, some not, flashing under MacosX is not supported for PCIe cards
- With Mac bios OF screen is visible, with PC bios it isn't
- If any of card doesnt work, please check/buy another one :)
- VGA, DVI works
- RadeonHD may work but 3d is not working there so R500 is the best option
- Most of Radeons need additional cable with 12V, make sure that seller adds it or buy, or make it
3. Add some supported Network card
- older Atheros pcie based WIFI or realtek 8168
- newer airports (WiFi) from x64 macs don't work
- Airport Extreme (WiFi) for G5 PCie is supported, it's not the same model as for AGP G5
- you may also try some USB network cards but they aren't reliable (or poseidon isn't reliable - who knows)
4. Turn on machine
5. Install MorphOS
6. Register MorphOS
7. RCTW looks odd on R500 (in 3.12-3.14), 3D rendering is fixed in MorphOS 3.15
8. Audio ports handling has been fixed in 3.15.

Please post any photo of card which work here, i'll add it to the google gallery.
Q&A:
1.
Q: Why G5 PCIe?
A: Because it has 4 USB sockets instead of 3 in G5 AGP!!! (additionally 2x more Cache per CPU, lower temperature and 2x more FPS in Q3, faster transfer to gfx memory so also faster scrolling in OWB)
