Huge, impressive, expensive.
I don't really like the layout of the drive cages and front intake fans. And they're not easily swappable.
I don't like the rubber dampers on the PSU and HDD cages. These parts won't oscillate or rattle if everything is properly secured and functional, if they're wobbling off balance then noise levels are the least of your concerns. I vastly prefer the PSU have proper electrical ground on the metal chassis (and mobo standoffs), I expect HDDs and SDDs might have better odds of surviving electrical anomalies when they are also properly grounded onto a large mass of chassis metal. And only a fool wants multiple floating grounds when a single unified ground works more reliably. (Yes it's nitpicky neurotic hypernerd stuff, but my hardware is complex and it ain't cheap and many problems can be so very easily avoided.)
I do like the sound suppression, though it will add some heat and more fans equals more noise so ... hard to judge the effectiveness (or limits) of the sound suppression. Won't do a lot of good if fans are mounted right under rads where they'll just push half their noise out of the chassis anyhow.
I also like those nifty metal feet.
This case has appeal but I think the Obsidian 850 or 900D already covers my sort of niche fairly well. If I wanted bigger and badder I would go for a proper "4U" server tower of the sort carried by SuperMicro, Dell, or HP - it would provide a lot more user-configurable modularity (or custom order specs) and the very best of the best chassis features, amenities, and capabilities at comparable cost (although I admit that few of them are available with all-black interiors).
