I just asked ASRock sales via [email protected] email address if/when ASRock would be releasing an ITX motherboard for the AM4 platform. This was JC Chung's response:

Yes, my name is Payden.

I am excited for this ITX board, but was hoping for some magic to be done with the X300 chipset boards. I figure since the chipset would be very small, you could fit other things on the motherboard that you normally wouldn't see in an ITX form factor.

Say:

A second PCI-e slot (look at current ITX motherboards, remove the chipset, and you have just enough room for another slot imo).

A second M.2 slot, or added USB functionality.

Four RAM DIMM slots.

You get the idea. Something ITX normally doesn't have.

JC's logic for going for B350 on an ITX form factor makes sense. Unless you consider external GPU enclosures via Thunderbolt or USB 3.1 Gen 2 (if this board would have a port for that).

Still, I'll probably grab this ITX board before switching to an X300 chipset ITX board once they are released just so I can get a PC again for a while.
