If you have room, check out the debian-based side of life with Gentoo. http://www.gentoo.org
Debian-based? Gentoo is not Debian-based, or even inspired. It's package management is more like FreeBSD's on steroids. Unlike Debian, it is primarily a source-based distro (with some binary packages, from the freeware, but not FSF companies) with some allowances made for binary packaging.
IMHO, it is the best Linux distro currently in existence (it's what I'm writing this on).
