Oh, look, it comes with a free pair of Rubber Dummy Loads™. I'd rather they give me a pair of wire antennae like are inside a laptop so I can just tape them to the inside of my case. It'd save me space on the i/o panel for something more useful.

is the AC wifi the only difference between this and the original MSI H87i?

Can someone explain why all these mITX boards only use AC867 instead of AC1300? And when will we see HDMI 2.0 capable boards? :)

It's the difference between 2 and 3 MIMO. If 802.11n is anything to go by, the desktop equipment will be overwhelmingly two-antennae parts. As to why, only the motherboard OEMs can say for sure, but if I had to guess, I would bet it has to do with the fact that antennae cannot be integrated in a build-your own setup, so they go for fewer antennae to save cost since diversity is not guaranteed and there is a large chance that the extra antennae are going to be redundant. In a laptop, the OEM can dictate the physical arrangement of antennae, so they know that there will be a definite benefit to having more.

As for HDMI 2.0, that depends on the CPU as that is where the display controllers are (for Intel anyway).
