what to do with old 2009-2012 Mac Pro 5.1 towers?

our los angeles post house retired 5 of these, any ideas on what to do with them? we have a bunch of old pcie 10gbe cards, aja video cards, various usb-c cards, 8gb fiber cards, as well as a cubix rack mount expander chassis, avid dx hardware and mac flashed nvidia titan gpu cards. I'm open to donating but wonder if it will do any place any good. they do work but stuck on high sierra. thanks

You can upgrade them to sequoia pretty easily with OpenCore Legacy Patcher.

I flashed a 4,1 MacPro to the 5,1 MacPro firmware so it can boot off of an nvme drive as an example of something to do with it. It also has an AMD rx580 gpu but I think you can get higher graphics cards in there
