> 768GB of RAM is insane.

Before this price spike, it used to be you could get a second-hand rack server with 1TB of DDR4 for about $1000-2000. People were massively underestimating the performance of reasonably priced server hardware.

You can still get that, of course, but it costs a lot more. The recycling company I know is now taking the RAM out of every server and selling it separately.

Apple hardware is incredibly overpriced.
