I'm building a Proxmox system and am having trouble finding a case that meets my needs. I require a case that is equal to or less than 16" x 11" x 23" (Depth x Width x Height) that can fit an ATX board and ideally three or four 3.5" drives (no PCIe Devices planned though). It also needs to be able to lay on it's side on a shelf, so ideally it should have front to back cooling. It will be living in a utility room so it doesn't need to be pretty.
