I got a 500, the weird floppy/stand thing and a C= 590 HDD. Funny thing is I don't think you can use the stand/floppy thing and the HDD at the same time!
In any case, I'd been talking to the owner of that stash ever since the post first went on Reddit; I'm a mod for that channel and have to keep tabs on that content fairly regularly. He got all of it at an estate sale in Wisconsin. From the sounds of it (he's a very nice guy who is not in the Amiga scene at all) he's about 26 years old. This is all new to him.
In any case, there's also a BOXED A2000, BOXED 1084 and 1080, and some more odds and ends. I just can't justify any more CRTs or big box Amigas. If I lived in Wisconsin I'd probably grab more but the shipping of CRTS is both dangerous and really expensive. But when the weird stand thing shows up I'll take pics for everyone here and see if we can learn about its history more.
Looks almost homemade. It's solid, but not exactly the prettiest thing. That stand actually comes with a massive power supply replacement.
