an operating system just for them: http://www.sourcemage.org/
I haven't tried it for myself.
If there are any nerds more into SF than F, there is a close cousin of
the above: http://www.lunar-linux.org/. They aren't as out in the open
with their Comic Book Guy nerdiness; just dig a little further down.
Again, I haven't tried it for myself. I'm not that much of a nerd,
although if you took away my Gentoo I would give these guys a try
(though I don't think they have native 64-bit support yet).
