That Zalman has some good things like lot more space and less bling-bling than other previous Zalmans but there are still negatives.
hot swappable ability on this case interested me.
Untill you remember that after all you don't have to swap failed HDDs that often...
And that some plastic trays aren't exactly part of quiet HDD mounting.
And if you look carefully HDDs don't have really any cooling. Sure there's mesh in front of them but negative pressure cooling just ain't gonna draw air past them with that leaky back and bottom of the case. Also hotswap backplane further blocks cooling and plastic trays prevent conductive cooling by case.
Also those restrictive meshes of fan vents (like any obstacle near fan blades) cause turbulence noise so they would need cutting away... And there's still plastic bling-bling surface.
For quietness Antec P18x is really hard to beat, especially considering its heavy multilayer panels don't need damping to be able to resist vibration and block some sound from escaping. But it's just hardly case I would call as spacious.
In general there are very few silencing friendly spacious full tower cases, thanks to magpie's nest fashion with thousand and one holes everywhere. Also door is good at blocking noise of optical drives and in general lowers level of noise escaping through front by blocking direct noise escape path.
If some crafting doesn't scare Lian Li A71 would be good starting point after installing some real damping mats like BeQuiet Noise Absorber or Nexus Damptek. Probably even basic bitumen mat would work well because most improvement is needed in vibration resistance and adding mass achieves that... and as nice thing case itself weights only ~9kg so no worries about few extra kilograms making it as heavy as
undamped equal size steel case.
