The AP181's (mine anyways) are loud because of the amount of vibration. If your AP181's "growl" at full speed, then it's likely all of them are like this.
After lubing my fans, I put one of the AP181s on a wood desk, and ran it at full speed perpendicular to the Earth, and it sounded almost identical to it in my case. Then I lifted it up just above the desk while it was running, and It sounded like a completely different fan. Even at 1200RPM, it was near silent, or maybe it sounded that way since all I heard was air moving. Even that was feint. I did the same test, but with the fan parallel to the Earth. I used two fans underneath the bottom corners, and one fan under the top middle of the fan frame to give the AP181 breathing room. The results seemed the same to me. Notes: The fans made the same vibration noise when they were new, and when they were lubed IIRC. Also, the AP181 continued rotating ~18s after removing power in the perpendicular position, and ~12s-13s in parallel. I wonder if that even means anything...
So I would recommend you use something to reduce the vibration. For example, silicone fan mounts. Those ones are ehume recommended. I can't comment on their effectiveness (haven't bought them, yet), and maybe they are less effective when the fan is putting it's weight right on them (parallel to Earth).

BUT, if you like a really REALLY LOUD case, it does offer you plenty of places to mount ALOT of fans that doesn't really improve the overall cooling performance by much......
The 3rd AP181 of the FT02 and RV02 is cooling the HDD's, so I don't think it is helping the GPUs much. Also, the motherboard tray is larger. There is basically 5cm of wasted vertical space for ATX users, which could have been used to move the fans closer to the mobo. If that space wasn't wasted, I think the RV03 would have performed similarly, assuming you block off the "extra holes" which let the air escape a bit early. AFAIK, the extra fans don't do much of anything. Maybe when all the fans are turned way down it would help.

Agreed. I keep mine bare so it doesn't look too flashy No top cover, no top fan or grill, no extra PCI slots covers, no front 5.25" covers...
I hope SilverStone makes a much improved RV03 (thermally, functionally, ect), but in an mATX form factor(and an ATX variant if possible), slimmer (maybe AP141s?), smaller in general, all aluminum, and with external WC in mind.
