Not the best choice I ever made. Gigabyte don't say its for standard cabinets only, CCL only sell it so stand by advertising from the blurb given. It fits works in an ATX case but there's no mount plate in the kit to hold it and moreover its a mare to get anyone to tell you that! Its not missing, it just doesn't come with one. Or a screw to hold any bracket in place. And the standard answer from all parties is we didn't tell you there was one!
At least Intel are on board and have updated the firmware twice since. The BT is now 5.1 but only as good as the 4.2 I had so the 'beamed' blurb is just blurb.
