Changes

There weren't any particularly noteworthy things about the hardware build. The GPUs need to go in slots 1 and 3, which means they sit tight on each other. We put the Titan XP Xp in slot 1 (and plugged the monitor into its HDMI port), because then the fans for the Titan RTX (which we expect will get heavier use) are in the clearfor now. The case fans were set up on in a push -and -pull arrangement, and the hot-swap bay was put in the center position to allow as much airflow past the GPUs as possible.
