Smallest ATX Case? HAF XB EVO alternative? Desktop cases?

[manuv]

I'm coming from a HAF XB Evo and want to make a new build that utilizes an aio cooler - and want to find something newer and similar that will allow for A) horizontal mobo placement with i/o ports on the back (similar to the XB evo). B) Supports ATX mobos

 

Is my only option here to downsize to an matx? What cases are out there like this?

And place it with the orientation you want ofc

 

Basically it's an ITX case ie smallest size but fits an ATX mobo and while it is not that similar to the XB evo it is the closest to what you are asking for that I can find
