From Hexus, I agree:
- that that LED fans need to go.
- Air filters everywhere
- a slim ODD bay below the MB, BUT it should have a permanent screw down "blanking" plate that mounts like the optional top fan blanking plate on other cases.

I would also like to see:
- an optional drive cage and and power supply hole blanking plate so I can mount more drives there and use an external power brick
- and optional drive cage that mounts above the motherboard so I can use drives there instead of a graphics card.

Or
Mount the motherboard upside down at the top. That way the fan exhausts both compartments AND leaves a nice open space to stack op optional hard drives.

Yes, I like to pack many hard drives in small cases for home media servers.
