rtrski :
Could you please clarify about the 'could fit EATX motherboard but no support'? (Paraphrasing). I've seriously considered re-housing my current build into this case with the one exception being I have the MSI X-power AC EATX motherboard, and all the specs for the case promise only ATX compatibility. A couple missing standoffs alone wouldn't be enough to stop me...just have to support the backside when plugging in things like CPU, RAM, etc. But if it physically interferes with getting the case built, that's another story of course.
To be clear,
your board will fit this chassis, and the chassis has all the standoffs for your board. Likewise, your board isn't actually EATX, it's a prioprietary depth in between ATX and EATX. It's only about an inch deeper than ATX, and far less than the 13"-deep EATX specification. Take a look:
You can clearly see that there's around 3" of extra space in front of the board, at the closest corner
Here is an EATX board, with the extra standoffs:
The reason for these lengthy discussions is that a case must support the above board to be labeled fully EATX compliant, and must have standoffs 12.7" forward of the rear edge. Since a 10.7"-deep board doesn't cover those extra standoffs, it doesn't need those extra standoffs.
