Has anyone done this on s19 models?
No and it won't be for a long while. Unless you want to have a "space heater" that even downclocked using 2000-2500W of 220V power that still requires a deafening fan from both the PSU and miner itself at your feet. This is for old gear that you aren't trying to get massive hashrates.
If we go by factory specs (3300W) a single hashboard would be about 1100W, so its not impossible. With decent firmware you can probably lower it a bit more. Of course those PSUs i don't think work at all with 120V so in American electric type countries you would need to plug to the a/c dryer range whatever circuit that brings 208V~240V (two phases).
My guess is that two fans in a pusher config (like the S15) should do. How loud? needs to be tested...
The PSU will be underused, so maybe you can remove or disconnect two of the little noisy fans as well. Of course you could still remove all fans and do the larger and slower inline duct fan method.
