SN30414 belongs to Neal Wilson.
The picture below is just a generic 2 PlayerComputer Space image, I have not heard back from Neal yet regarding his machine. He posted a message on the Google discussion groups back in 2002. Here is his post.
I tried emailing Neal to get more information about his machine, but his email address firstname.lastname@example.org seems to be inactive. If he ever sees this site, I hope he emails me.
