There is always the option to go custom SFFPC. Like mine that is build in a NFC-4TF is quiet and would be able to have a RTX A2000 and a Ryzen 9700x no problem (a 9900x would be noisier)
Ir also there is that miniPC I just saw today, with is with a Ryzen AI9 HX370. Not as bananas as the upcoming HX395+ CPU power wise, but would still be powerful, and pitentially quietter with the custom case created here.
