Hello there,
Just leaving my comments as recommended by Gigabyte's RMA service. I am rather pleased with how quickly Gigabyte have been responding to my emails.
I had my UD7 (rev 1.0) for 2 and a half years and a component had burnt out. Unfortunately no longer manufactured, Gigabyte offered a UD5 (rev 2.0) and G1 Assassin. As my case can't hold an XL-ATX motherboard I happily accepted the UD5 (my home server has one -- has been highly reliable).
Thanks again Gigabyte for your excellent RMA service. Happy customer here.
