Just confirming that the Gigabyte 9070 non-XT card fits. I have an older M1 V2, unmodified, no fancy cables or cable management. I had to remove the front panel cover, front bottom feet, and front port assembly to get the card into the case - you'll have to angle the card in, and I needed the hole in the front of the case unobstructed to do it - but once it was in I was able to put the ports back.
The Gigabyte 9070 XT card is the same length and width, but listed as 6mm thicker. Looking at the end of the card in my case, I think the XT card could fit but it's going to be right up on the cable coming out of the front panel for the dual USB ports. See attached bad picture.
The Reaper is shorter and should fit no problem. The Sapphire Pulse 9070 (non-XT) should also fit easily.
