Thanks for sharing! I know the 5090 FE version is probably unfinished yet but it appears to support 3-slot so I'm very eager to try it out.
One problem is many cards' PCIE bracket goes a bit over the backplate so the frame needs to be thinner at the contact point.
Then there is extra space behind the motherboard but that does not help add cpu cooler height. Adding another short PCIE card (R33A-AMP or R33A-ADT no difference?) will push the GPU to the left and create extra 20mm for the CPU cooler. (I think that's how fractal ridge does it)
Hope the official version is coming soon!
