DAN A4-SFX @ TechPowerUp
 

The Dan A4-SFX V4.1 is the smallest ITX chassis with full GPU support that we've ever reviewed. It also manages to walk that incredibly difficult line between the smallest dimensions and uncompromising SFF component support alongside full-length GPU capability. On top of that, it also performs extremely well with even big-boy hardware.
