New power tray
Gone with the gang of DC power adapters, in with one of the original drawers plus an Antec 650 W PSU. The sides have been trimmed away to allow for side airflow. One of the 4-pin 12V outputs feeds a bus of 4 systems, soon to have a mate on the other side. Since the terminals only need an inch or two of clearance, I am building a smaller tray to set above it for the ethernet switches.
I could use the PSU cable to feed a motherboard since I get it for "free" and it would allow me to power on the PSU to everything via WOL, but I decided not to in order to keep things neat and easily accessible. Maybe later I'll rethink this; also there's no easy way to slide the tray out or replace the PSU without disassembling things.
