The Blackmagic is a fair price, if it delivers on being quieter and proven to work with Mac. It competes with the Aorus Gaming Box, which is another all-in-one that is smaller and 200 bucks cheaper, but is reportedly very loud, even when the computer is SLEEPING. The Aorus is kind of upgradable, but it takes a small version of GPU cards, not the normal size, and its PSU can't drive a Vega, so its not truly upgradable. The Sonnet Breakaway with RX580 is $550, but much larger in footprint, and again, doesn't have the power to run a Vega, so maybe it's only upgradable in theory. They do sell a higher powered Sonnet WITH a Vega... but it's $1,300. Explains why Apple went with the RX580.
