Folks, has anyone tried using one of those 5V DIN rail-mounted PSUs (eg Mean Well HDR-XX series) for powering the boards and HDDs? My "server" stack has grown to 10+ boards (many thanks to this forum!) and I am thinking of getting a couple of powerful industry-grade 5V units, but not sure if they provide computer-grade output, especially 12V for HDDs.
Any thoughts?
