When they were discontinued, I was allowed to take some of them home. Had to give them up, though, because I lacked the room to keep the boxes around, and at the time I also lacked the time to maintain software or investigate hardware upgrades.
The saddest thing for me is that today I would love to have kept the enclosures and PSUs (I’d likely have stuffed them full of Raspberry Pi compute modules, or Celeron mini PC motherboards, and hooked up an MCU to the display and buttons…)
But some of them were online and running at my former employer until 2018 or so, which is nothing short of amazing.
In case someone is interested, I have a bunch of old resources here: https://taoofmac.com/space/com/cobalt
I also kept a copy of the hacking FAQ: https://taoofmac.com/space/com/cobalt/faq
