https://hdplex.com/pub/media/image/Product/400WATXLPSU/installation/12.jpg eyeballing this, it seems like a rather shallow ATX case ... would anyone know which one it is? I know the PSU is a hdplex one that's not the question...
Yesterday I found a <20L ATX case https://www.advantech.com/products/1-2jkemv/ipc-7120/mod_5cc7223e-b2f1-4acf-87de-87a785fe460a it uses a flex ATX PSU to get there. The drive bays are removable and then you can fit pretty big tower coolers in there. Alas, it's stupid expensive. And yes, I am aware of the Cerberus X, doesn't stop me from hunting for moar compact ATX cases.
