[NAME]    All the official pics I've seen show 2x2.5" SSD drive cages to the side of the extra PCIe cooling card. Here is an "unofficial" pic that may help you decide. As you mentioned, there appears to be plenty a width room for 3.5" drives, but 'zero' additional thickness. (photo by TurbsTheKatLove) (click photo to embiggen) [IMAGE]
Currently have an Aurora R6 with 2x4TB 3.5" SATA drives for data and storage, thinking of upgrading to an R11 with the liquid cooled graphics card option.  All the official pics I've seen show 2x2.5" SSD drive cages to the side of the extra PCIe cooling card. Does anyone know if there is enough room to put 2x3.5" SATA cages in place of the 2x2.5" SSD cages?  I already know they're interchangeable as far as width and mounting screw location.  But is there enough room to fit in the beefy graphics card and cooling unit along with my existing SATA drives?  Or do I have to swap those out for SSDs? Anyone have this Aurora R11 configuration and can try to swap their 2.5 and 3.5" cages to fit check?  Or already tried it?
Aurora R11, GTX 2080 Super (LC), add 3.5" HDD cages?
