Well it's bound to appeal to collectors.
That's who it's targeted at, if they want to spend their hard-earned on an old box that's upto them.
At least the owner didn't just recycle it, and is offering it out to someone who wants it.
Just because it isn't being given away doesn't make it wrong.
I can see where it might 'feel' wrong, selling something that most would have thrown away a long time ago, but to the collector, this is just as valid a piece of history as the actual system itself (more so because by it's very nature it's rarer!)
At the end of the day it's just a box, who cares.
