We did a very very quick research during CNY.
AMD 2200G box fan is so high that can't be installed into our chassis.
BUT... how about install CPU fan and heatsink separately? HAHAHA...
Only for fun
That fan has an external shroud with AMD logo that is making it this tall. Some users stripped this shroud away to fit this cooler inside inwin chopin which looks to be designed to fit reference 47 intel cooler:

I understand that you cannot support such configuration by instructing users to strip down their BOX fan, but you could provide a replacement fan like this:

The question is if the access to the fan screws is blocked by this shroud or not.
Btw if we are talking about new form factor, rather than STX, It would be nice to see a dual slot ITX board - just by adding second slot (which probably required more layers in pcb) and bifurcating the original slot depending on configuration. This would fit in all itx cases supporting dual-slot GPUs, would solve the issue of 2cm pci-e extender required when you use angled pcb riser, and obviously would enable support for two add-in cards without adding a bifurcated riser. With such boards, I'd love to see a 'console' configuration with 8+8 config where first slot is occupied by two M.2 SSD's on a pci-e adapter without a bracket and the second slot is occupied by the GPU. Sorry for going offtop though
But well, for raven ridge the mini-STX seems like an ideal match
Zalman CNPS2X will be better choise. The same profile as A18, but not so noisy.
In our tests CNPS2X was terrible. We have picked it for tests since it was in original Steam Machine prototype assuming that they did a good research on that, but it seems like it was one of the reasons that reviewers didn't like the prototype. It was really quiet, almost silent, but at the same time the 65W i7 would get hot really fast on this. I think that this is a cooler that would do good only on a 35W CPUs...
