Currently there are no specs release for the C4-SFX I am working on. The specs in the first thread post are wrong. Furthermore you will have to wait minimum 6 month from now on before you can hold the case in your hands. But to answer your question: The case has two possible GPU mount points horizontal or vertical.
Specs for vertical (sandwich): Length: 300mm Width: 3 Slot Height: 150mm
Specs for horizontal (classic): Length: 300mm Width: 2.75 Slot Height: 115mm
*There is no guarantee for these specs.
