If you want to build one for the 5080 Prime that would be sweet in my mATX build. Then the CPU, RAM and GPU would all be custom loop in a SFF chassis, which is extremely rare. The Phanteks XT M3/V3, O11 Mini and Gamdias M4M are only a few SFF cases that are designed with enough intelligence to allow such a build. It allows you to compromise a whole lot less than SFF typically demands. I don't feel like I am missing much or making concessions/sacrifices for the sake of size.
