I can't believe they are shipping it with a PCI 3.0 riser cable. Granted, not all GPUs right now need more than PCI 3.0 x16 bandwidth, but surely if you're building a new rig today, you should get at least a PCI 4.0 riser cable. That would keep this case viable if you have a GPU that requires a PCI 4.0 x16 connection.
I find the concept interesting, but I can see a couple issues with the folding. Feels like it would be easy not only to fold in the wrong direction, but also to bend parts. I also kinda have concerns about airflow for both the CPU and GPU. Especially the GPU. Might be overthinking on this one.
Lastly, what kills the cases for me, though, is the color schemes. I personally find them atrocious...
