What are these?

I am trying to figure out what these 2 white metal boxes are. I am looking at buying a red sea reefer setup from someone and I have no idea what they are tbh.

Top 2 boxes look like older Ecotech Radion power supplies. Bottom right box is an Ecotech battery backup. Blue parts on the top left look like parts to an Ecotech Vectra return pump. Small white box on the bottom left looks like a controller for a DC skimmer.

Thank you so much. That helps alot, the listing wasnt super clear on everything.
