Pro The best features of Arch without the hassle
ArchBang is minimal but completely functional out of the box. It's still up to you to set up to your liking. You still get Arch's unmatched documentation, insanely vast number of packages (in AUR) and extreme customizability. And a small but friendly and approachable community.
Pro Rolling release
Being based on Arch, Archbang follows a rolling release schedule, ensuring that the software will always be on the bleeding edge.
Archbang is a pretty lightweight distro. It uses Openbox as a Window Manager by default, without having the need to use a desktop environment which would only bloat the OS further.
