I still haven’t been able to find something that fits the bill - the hardest part to get information on is noise, since most people don’t seem to care about it or just play with headphones. I understand that such a product is hard to build, with a direct tension between power, space and noise.
What has never been clear to me is whether such a market even exists and I’d tend to say no, even if the market seems to be changing rapidly with amd apus ( we’re far from a 5080 , but it seems to be a step in the right direction ).
