I like the idea of the hard riser being less error prone, and I wonder if the C4 layout with GPU on same side as CPU will help improve thermals for the m.2 SSD's controller at the back of the motherboard. Personally, I'm not too concerned with showing off GPU in a case this small and would always prefer the vented panel for better airflow anyway. Having 2.75 slot width available for GPU does appear to be quite relevant for the long term though.
