Not sure and the manual doesn't really state why either.
Funny you mention the Gigabyte 970 mini, I was looking at that one and other small form factor gpus and noticed Asus is coming out with one too.
It would be cool to see a comparison test review!
Haha! Yea two things about the CPU cooler I'm kind of worried about:
The manual prefers not placing it the way I have it installed as "it may result in reduced cooling performance";
The pipe ends are super close to where the GPU's backplate will be.
It'll be a tight fit, for sure. Thanks!
Thanks! Hopefully there will be some sales over the holiday and the 980 drops in price. Can't wait!
