This one?

2.5 slot, ATX Dimension: 306 x 135 x 49 (mm)
It is too long by 1 mm since we are supporting cards up to 305 mm, not sure where it is measured so if that's with the PCI bracket, then it would be within the 305 mm
It is too tall by 5 mm because we are supporting up to 112 + 18 mm so in total 130 mm IF there is a recess for the PEG connector and there is one.
It is too thick - we are supporting 41 mm wide two slot cards, if you go with 49 mm card, it may fit, you may have issues while installing it because there's a 45 degree bent edge that will prevent you from sliding it directly in, but more importantly your fan blades will be so close to the perforation they'll scratch themselves against it and/or the turbulence because of being so close to it will make it run loud as hell.
Sorry for not adding this card to the list, but Sapphire's website is weirdly organised right now and I didn't notice there's a nitro 5700XT when updating this lineup.
