I am trying to find a 4u rack case to move my old computer to. My problem is that the computer will be pretty mouch always on and it will run in the room I sleep in. Because of that I need a case, that will be as quiet as possible while housing an ATX motherboard, ATX psu and a GTX 1070 founders (270mm gpu length). I would welcome 8-16 HDD slots. In case that would create problems with loudness I can also get a separate JBOD and a controller, however I am not sure wether that would be any quieter and it would deffinitely be more expensive. Price is also important, but I will gladly pay a hundered dollars more for a quieter case. the 4U size is also not necessary, however I would prefer a larger case to have more space to work with inside the case. 3U would be pretty tight and I have plenty of rack space.
