Ari,
With the migration towards ITX do you still see there being much of an enthusiast space for mATX? It almost seems like no-man's land for this segment. I love the looks and without any decent viable mATX boards supporting the Ryzen 200 series I wonder if it makes sense to use an ITX module? But then it seems overkill in terms of storage and space.
The 3-sided glass panels look outstanding but I wonder how airflow would be affected along with temperatures and acousics.
Actually, there are now some great mATX boards for the Ryzen 2000 series - they've literally hit the market over the past week. I think that's a great use case for a micro ATX case. But yes, generally there has been a trend towards ITX as the importance of expansion slots lessens. What mATX gives you, however, that ITX really can't, is ease of use in with a lower footprint than any ATX case. ITX cases always require a bit more work to build in.
From my preview of the LD01 case at CES earlier this year, I'm pretty confident that thermals will be more than adequate, but that's something that could definitely be examined if a TBG review goes forward.
There are a few other reviews in the works right now, but if TBG does another case review in the near future, it will probably be the LD01.
