X870e Godlike Motherboard + Xtreme Waterforce WB 5090 + M.2 Xpander-Z Slider

MidnightStorm

So for my build I'm anticipating using the Lian Li O11 EVO Dynamic XL case with the MSI MEG x870e Godlike Motherboard (default position). I want to use the Gigabyte AORUS Xtreme Waterforce WB 5090 and vertically mounted it while also still using the M.2 Xpander-Z Slider that comes with the motherboard. I've made a diagram that leads me to believe I'd have the clearance in the case to do so until I remembered it's a dual chamber case which leads me to assume the 304mm width is for both chambers and therefore I cannot find the width of just the main chamber to still be sure I'd have the clearance based on where the vertical bracket mounts in the case (highest position) and where the bottom PCIe slot on the board falls in relevance to the bracket. Initially it seemed I'd have just enough space (or ample room depending on which slot of the bracket I set the GPU in) even if the bottom PCIe slot on the motherboard would be behind the GPU to still use the Xpander but now with all the research I've done and now lack thereof in finding the internal dimensions for the case to ttriple check everything again, I wondered if anyone here may know the answer.

TL:DR I need to know if I can vertically mount a wb 5090 on the X870E godlike motherboard while still having room to use the included Xpander M.2 storage card in the main chamber of the O11 EVO Dynamic XL
