I currently have the the Cooler master CM690 II (mid tower) which comfortably holds about 8 3.5" drives and the cooler master Cosmos II which with a little modification comfortably holds about 16 3.5" drives. I'm looking for a case that isn't as tall as the CM Cosmos II (and has more modern front ports) but holds about 12 3.5" drives. I need 12TB drives so I won't be using 2.5" drives. I do not have the space for external storage arrays - I need to replace my CM690 II models with a different case that holds a few more drives.
