Read this review http://www.hardwarecanucks.com/foru...srock-fatal1ty-z270-gaming-itx-ac-review.html and get the Asrock Fatal1ty Z270 Gaming-ITX/ac instead. Asrock has really gone high end with the components used and it still has a usb 2.0 header. If you read through this thread you will find many people having issues with the Strix.
True, but the people who post are the people who have issues. Personally, I haven't had a single problem with my Strix. (Except for having it default to RAID the first time I installed windows.)
I've questioned whether I made the right move in not going with Asrock. I've been a huge fan of the brand for years now, ever since z77. So why did I switch? Having the extra USB port on the back is nice, since I don't need a USB 2.0 header.
This time, however, I was mostly swayed by the looks. I ordered a white Sentry for my build, and decided that, as the first really nice case I've ever had, that it was worth showing off a little. I wanted my build to either use purple or nvidia green as its accent, so both not having the red accents on the motherboard and, I admit, the RGB header, was a nice perk.
If the Fatal1ty had an option for black accents, or white accents, I'd probably have gone with it due to the better M.2 placement.
