Extended ATX Case Compatibility

[ObsidianObelisk17]

I got an Extended ATX motherboard today, and I was searching online for a compatible case, preferably a 2U server chassis. I have found many different cases, some compatible directly with E-ATX, and some without it listed as a compatible form factor. More of the compatible cases are proprietary cases that require you to call and get a quote for, so that made me reconsider some of this. Are there any other form factors that will be compatible enough to hold it? I've noticed some similar form factors have similar screw layouts, which would be able to hold it in place at least. I just need a case that can hold it in place, I don't need the board absolutely anchored in place. This computer will be a throwaway rendering computer made with secondhand parts.
I'm just asking for comparable form factors that would have at least 4 matching screws. This computer will be used just for me, I'm not building the server for a company or anything fancy like that. I an decently experienced with computers, so don't hold back any technical comments or questions.
