If your goal is as close to noiseless as possible, a big case with a lot of sound dampening material is the way to go. However, the modern SFF experience is much better than you give it credit for. An AMD 5950X with a 240mm AIO in a mini-ITX case is easy these days and it keeps the CPU temperature in a reasonable range. But if your goal is a no-compromise quietest build possible, obviously you don't want to get a sma…

I could have been more clear here, I meant a custom-loop, not an AIO since they're a sidegrade to a top-end air-cooler at best. > However, the modern SFF experience is much better than you give it credit for.

Custom loop and an AIO of the same size are going to perform the same. I don't understand why you're suggesting that water cooling costs "10X" as much as air cooling when that's clearly not true.
An AIO and a custom loop with the same size radiator will perform the same. I've done custom loops and I've done AIOs. There's nothing special about a custom loop other than you get to mix and match different components.
Also, the top-end air coolers like Noctua perform almost as well as liquid cooling these days.
> I don't see the contradiction - you can have a quiet SSF build, and you can have pretty powerful SFF builds (enthusiast GPUs might be a problem), but you can't really have both at the same time... at least not under load.
I'm telling you - I have a 5950X and a 240mm AIO in a SFF and it's quiet. I could move the same CPU and the same AIO to a big case with sound dampening and it might be marginally quieter, but not by a huge amount. The only real difference is when I'm running the GPU at full tilt during gaming, but it's undervolted and I can't hear it over the game anyway so I really don't care.
