Although officially produced in celebration of the Twentieth Anniversary of Apple, the 20th Anniversary Mac was released close to a year after the fact, in late Spring, 1997. And a truly unique Mac it was. The Motherboard was similar to that of the PowerMac 5500, and it was based on the same 603e processor, running at 250 MHz. The real innovation of the 20th Anniversary Mac was its unique shape, and advanced sound and video features. It came with an integrated TV/FM Radio System, an S-Video Input, and a custom sound system designed by Bose, with integrated stereo speakers, and a separate sub-woofer (it also included a 33.6Kbps GeoPort modem). The Twentieth Anniversary Mac was a limited edition, and sold for nearly $10,000. Its price was cut to as low as $1,999 and it was discontinued in March 1998.

I just wanted to add a comment about the 20th Anniversary Mac. I was actually selling macs retail at the time of it's release and there was a very Apple-esque promotion based around the celebration. You mention that it started at a retail of $10 K. But what this included was that a limo would deliver the Mac to your house, and a man in a Tuxedo would set it up for you. We only had one customer who actually went through with this, but as far as I know, the setup was delivered as described. Not bad for $10 K.
