"They don't mention much about the actual quality though. How efficient is the power supply? How many fans does it have? Any sound insulation inside? Maybe a aluminum/plastic/aluminum sandwich for sound dampening?" You get that this is open hardware right? You can go to https://github.com/system76/thelio/ https://github.com/system76/thelio/ and see the whole story (there are separate projects for Thelio Io and the specifics for each model, but you get the idea). They even have a BOM: https://github.com/system76/thelio/blob/master/Thelio%20Common/Bill%20of%20Materials%20(BOM)/thelio-systems-bom.csv https://github.com/system76/thelio/blob/master/Thelio%20Comm... Here, for example, is all the detail you could hope for on the PSU for Thelio Main: https://github.com/system76/thelio/tree/master/Thelio%20Main/Thelio%20Main%20Power%20Supply https://github.com/system76/thelio/tree/master/Thelio%20Main...

https://www.tomshardware.com/reviews/fsp-dagger-600w-sfx-psu,5033-11.html https://www.tomshardware.com/reviews/fsp-dagger-600w-sfx-psu... is a review of SFX the psu used, I assume in the smaller case. Quiet, but not the best. The other psus in the BOM list are excellent EVGA units, oversized, and they picked the older G2 model - which is good, the G3 has (or had?) issues with the fan curve and can be loud. The G2 is reasonable quiet as well. The Arctic case fans are not the very best but very good for their price, reasonable choice as well. I use them myself, in my very quiet PC. I don't see sound insulation in the BOM, I might miss it. But the regular customer hardware used there I can judge seems very reasonable picked. Not the usual bad cost optimization you see in regular pre-builts.

I'm not seeing the schematics for the PSU here. There's plenty of detail I could hope for that's not there.

  And if the schematics were there, you'd hope for a complete metallurgical breakdown of each of the wires inside. ;-) If went out and bought the PSU yourself, you wouldn't have any more information. I think that's a reasonable standard to hope for.

    Er, no I wouldn't. Nobody is claiming that that forms part of an open hardware definition. And yes, PSU vendors aren't advertising their products as open hardware. I'm aware of this. So people shouldn't be making out that this PSU is open hardware. It isn't. Whether or not people are fine with that is up to them. Personally PSUs are on the bottom of my list for things to care about the openness of.
