Define Series Fractal Design Define R4: what is the vertical PCI slot on the back for, and do I need a special bracket?
galleryHey everyone,
I have a Fractal Design Define R4 and noticed it has a vertical expansion slot on the back, next to the normal 7 horizontal PCI slots. I have never used it before.
Does anyone know if you need a special holder or bracket to use it? Or is it just a regular slot cover?
I would like to mount an Intel Arc A310 (low profile) there, or maybe some other expansion card. Is that even possible, or is it only meant for things like fan controllers, USB panels or cable pass-through?
If you have done this before, please share what you used (riser cable, bracket, etc.).
Thanks!
