I've got my two Inspur 12-bay cages set up with a rear fan wall/enclosure, an OpenJBOD board, an Adaptec AEC-82885T expander, a pair of cables from the expander to the top two SAS ports on each cage, an HP AC-063-3 A power backplane and 460W PSU, and one hell of a hack job of power cables...
It is a tad finicky at the moment (loose pin somewhere on the 12v power line to the fan controller in the rear fan wall, I think), and it's a hell of a rat's nets behind everything at the moment. But it's all working, my TrueNAS ZFS pools are happy, Plex is back up, so the kids and wife are happy, which means I'm happy.
Side note: locate LEDs work fine on TrueNAS Scale with encled
