I have to be honest.... I don't know that I'd want that for a main PC. and for a SFF I would want more air movement and to orient the power supply to remove hot air from the case as well.

Not going to lie, there's got to be a pretty specific use-case scenario for this. Put it in a gaimg rig and that heat is adding to everything else, which also means the silent aspect is defeated since either CPU or GPU is going to have to deal with it, and one of those is likely to make some noise.

1K fanless is a feat.

I agree, seems a bit niche, as once you get that large other components all have fans that make the PSU negligible.

Still neat though.
