My unRAID server has 12 data drives, 2 parity drives, and 3 SSD cache pools. Plus dual Xeons on a SuperMicro ATX board.
I currently have the Deep Silence 5 case by Nanoxia. But things are cramped. I’ve filled all the standard drive bays, plus put in a 4-bay 5.25 enclosure. But I still have one of the SSDs just floating around.
What would a better case to put all this stuff in?
I would put that in your original post next time. It’s hard to know what kind of things to recommend if we don’t know what you have already looked at. Knowing that there are standard ways of increasing drive count (such as the 4x drive pay you are using now). You can search by internal drive count and reduce your search significantly.
That said I think the fractal design 7 xl looks good.
