Anyone else have a motherboard whose slot was too thin to accept the wifi mounting bracket on x299 micro? Also, anyone else have a motherboard with no screws that fit to secure the IO cover?

Thanks for your reply. I managed to get the wifi bracket in with some "modifications". I wonder if the brackets for x299 and x299 micro are different or maybe I am just trying it wrong but because the io cover is installed now I can't really send a pic. The problem was the bottom most piece of the bracket that shoud slide through the motherboard would not go in. The hole was too small on the motherboard. But once "installed" I mounted the motherboard and the only screw that would not reach the stand offs was the one that needed to pass through to io cover. Pic attached.

I thought the same thing. I replaced the stand off, remounted the Mobo multitple times and still no luck. I guess it may be the tray but everything looks normal.

Yes it does. Fits just like the other screws.

Not likely, but if you think the installation of the IO shield could affect it that much it makes me believe it is the installation of the wifi bracket. It doesn't fit right, never did. The hole in the Mobo was not big enough for the bottom of the bracket to pass through so it may be misaligned. In which case where do I get a new slimmer bracket or a Mobo with a wider hole?

Thank you for the help. It ended up being the wifi bracket. It was slightly off due to it not fitting the motherboard correctly and it was pressing against the IO cover.
