Drobo

What to do with Gen 2 4D

I have a NIB Gen 2 4D Drobo and 4 Seagate Barracuda LP 2 TB drives I want to get rid of. Is there a use for such an old product? I don’t see a market place here and need to know what is my best resource for trying to sell this. I’m not on Facebook btw. Thanks. Stuart.
