Some nice improvements over the O11 and its variants.
Personally I’m done for fish tank designs but nice to see the column creating an almost sealed tunnel between the rear panel and the side fan bracket. Support for 140mm also a plus, without going too big on dimensions.
Clearance from floor is good, air filter implementation is good.
Like the fact that control and ports are on the top, as most cases now are designed to be on desks, despite some of their gargantuan size.
Would love to see the use of adjustable rails instead brackets, as any fan size wouldn’t be partially blocked. More of an issue when behind an intake fan (can create unnecessary noise). And some blanking plates to cover any area where the bracket is visible because of the fan size used. Aesthetics, I know, but as a fish tank, where looks is everything, the build should be as clean as possible.
