Haha, it looks like they could have fit that full-size 1070 in that case!
So, going by their measurements, the card itself would fit into the Logic Supply MC600, but you probably wouldn't have room for the power connectors unless you flipped it upside down. I'm not exactly sure how flipping it around would cause the bezel on the MSI card to fit in with everything but I think it might actually make the card fit better. as you could snug a flat surface towards the edge of the case instead of the beveled side.
I am confused which orientation you are referring to because I remember you wanting to flip the graphics card in the MC600 but maybe one of these adapters but 90°d the other direction since the MSI 8pin has the retaining clip facing away from the heatsink?
I found that by scrubbing the Modified PCIe 8-pin connector thread...still reading through it though.
