After 11 days in customs. I finally got my S1080 back yesterday and immediately installed Windows 8 Enterprise on it.
Gigabyte changed the outer shell it seems. Looks new again.
Problem is that I can't hear anything. Speakers are dead. I plugged in some external speakers through the audio jack and they are playing so I know that it is not a Windows 8 driver issue. If I am correct and they put my motherboard into another shell with speakers. Then the speakers in that shell were dead. Or there is some other explanation.
Going to log a ticket today.
