I'm working on the concept of a SFF case and trying to establish GPU compatibility but I'm still confused about GPU sizing. Finding measurements is not that hard but I find conflictual information regarding how the measurement is done, with or without the bracket, including the PCI-E contact point or not, not to mention that most free 3d models I found seem to be out of scale and they don't align to the reference full size PCI-E card.
The PCI-E reference document lists full size cards as 111.15 x 312mm, which is a measurement that excludes the bracket. Anyone can confirm this is the way GPU sizes are measured?
Also what would you think is a rational minimum requirement for GPU size for a 20L case?
