If you packed those specs in to something twice the size of the mac studio it would sound like a loaded up server rack on your desk. Yes you can get absolutely massive coolers which are quiet but nothing nearly as portable as this.

Do you have a reference on how quiet these are? I mean it’s fantastic if true but half the reason my MBP gathers dust is the noise under load compared to my (almost) silent 5950x under load. But yes it’s a big box that I have no intention of moving.
