Worst case would be short device not mounting firmly in any way (even if you stripped that plastic crap away) because of lack of full complement of screw holes.
And then there's this Chieftec's system... splendid sabotaging!
Must be that modern urbanized human has butterfinger in the middle of...
While for same fan static pressure scales in direct relation to speed blade design/geometry has as much to do with it.
S12's huge hole area betweewn blades and gap from blade tip to frame makes it leak air back with least back pressure or pressure difference between sides of fan. (that's also...
You live in cargo ship's engine room or what? Time to get your hearing checked.
1800rpm fan is as quiet as highway in front yeard. (unless it's 80mm/smaller with very little airflow per rpm)
Any impedance (restriction) in front of blades lowers fan's airflow and causes more turbulence noise.
And AP181 has such restriction built into fan meaning at same RPM it has lower airflow than exactly same blade geometry FN181. That factor is probably what shows in their account in their...
It's mid-tower and those have never been really spacious.
PC-A70/71 E-ATX full tower is for space:

Long graphics cards look almost short in them...
Too bad that half of the time innovations come from marketing wanting bulletpoint-engineering.
Like that HDD mounting system of PC-B70 is already halfway there: That unnecessary HDD caddy/tray only increases size of airflow obstacle compared to plain HDD with rubber grommet screws.
It's almost...
You should be more worried about buzzword design cases done just for the sake of weird design and empty marketing buzzwords.
Going from the PC-B70 to the Raven, I GAINED(!!!) about 7 to 10* Celcius on my CPU temps

Any design needs...
Besides that easier access compared to standard front-back mounting it's superior in space utilization efficiency by leaving more space for long cards with same external case depth.
But if not done properly it leaves more "room" for designers to trash airflow.
There are couple different sized versions from Chieftec's same "basic theme".
Replacing B/C serie models again have some clear differences to old D-serie at least in maxi tower.
Actual I/O port module is replaceable...
Bigger mid towers can fit most graphics cards but they definitely don't have much loose space inside because case has sufficient height only for PSU and mobo.
E-ATX full towers PC-A70/71 have space for up to triple radiator if you mod top or get "pre-modded" top panel.
Coolermaster ATCS 840...
Yeah, both overpriced as special designs mostly are...
E-ATX full towers PC-A70 and PC-A71 are in same price class as FT02, whose hefty external measures don't translate into equal inside space.
