Just a small info here, I'll extend it, when I've finished testing the system.
- Mainboard: MSI K9NGM3
- Audio: 7.1 analog / koaxial out
- Video: VGA / HDMI (supporting 1080i and UI2)
- Extras: 6 USB, 1 Firewire, eSATA
I can confirm, that the Fiire Invisible is working out of the box. However, the Lan Option ROM had to be enabled in the BIOS. The CPU cooler is a little bit to loud, maybe this can be adjusted in the BIOS (AMD cool'n'quiet...).
I don't know why they didn't made it available, but the Board also has an RS232 port. It is located near the keyboard plug and the BIOS shows it too, so it should be usable.
Update The original case looks a bit cheap. Anyway, It is good for hiding behind TVs.
As I'm using the components in an other case this doesn't matter for me. I changed the CPU cooler against a Scythe Shuriken, which gave very good result in both noice and cooling. In the new case, the RS232 is also usable and is working as expected.
