Ditto; awesome site. But the pages from early 1998 don't list the All-In-One at all though. Weird. About the accessories box thing - it's not the monitor I'm talking about. Everybody keeps saying that. Here's a picture I made in Photoshop of what it would look like:

And here's my response from the apple-history.com guy:
"Sorry. no, they never made one. The PowerMac B&W came after the iMac, which was, in effect, what you describe. But there was never a B&W all-in-one branded as a Powermac."
But I'm still not giving up.
