distro optimized for file server

[Andres Gonzalez]

Folks,

I have heard that there is a distro available that is optimized just
for a file server. Which distro is it?

I want to put together a box that will just sit on the network and
present some Samba shares. I want to run it without a keyboard or
monitor and be as maintenance free as possible. I recently built a
Fedora Core 7 box but that seems like it is a little overkill for what
I want.

Thanks,

-Andres
