This does look tempting from
Azza.

That has an ... interesting airflow design. At least there seem to be plenty of gaps, but the top fan exhausts upwards through some slivers of gaps above it in the glass, as well as the glass-less top area inside the frame. Tight, but it might work somewhat. The bottom radiator is clearly also an exhaust. There dont' seem to be more fans, as the other side has a HDD. So the GPU, due to being mounted horizontally like that, will recirculate its own hot air (hot air will rise, but those fans are pulling downwards, and fans beat convections 100% of the time), with the top fan only partially helping to move it away, and no major effect from the radiator. And given the complete lack of intake fans, the negative pressure setup will cause air to take the path of least resistance, meaning the vast majority of air being exhausted by the fans will enter the case through openings close to the fans, and the vents will be less effective the further from a fan they are (many cases, especially small SFF cases are built around negative pressure, but those place their passive intake vents strategically to ensure airflow over components needing access to air, which this very clearly does not). The GPU is about as far from a fan as you get in this case.
Overall, I predict this to be huge, loud, hot, but a good showpiece for events, YouTube or Instagram.
