Just saw this thread on the main page; That motherboard is impressive!
Without looking at its features and reading about it's stability, and just judging it based on the photos, it looks fantastic.
3 KG / 6 lbs is a bit absurd but dat aluminum is beautiful! As
previously mentioned, motherboard shrouds are great, when implemented properly. I was a sucker for the Sabertooth line up back in the day but the X79 intel platform just didn't offer the same level of quality that was in the mainstream platform.
I know most don't care but when you're paying big bucks for these products, and they perform similarly to each other, I am more inclined to go for the product with the additional shroud. Especially it's all from milled aluminum.
