I`m currently using Slackware on every server i have at home. And i used it since version 7.0. All old school console... no X, no GUIs... i manually pick every driver for every server and recompile the kernel to be lightning fast.
The best thing about this distro is... u actually know what happens with your system and once configured... ohhh it never fails. Never. I can forget that machine for years, still doing its job quietly and it just works.
My oldest machine is still alive and kicking.. i`m using it mainly for SVN mirror and local Git server. Here is the machine:
