Here is an understated Gentoo-based project Calculate Linux with its just release version 11.9. It is a source-based distribution aimed at businesses and 
corporate who prefer the flexibility of open-sourced software (low cost price, minimal hardware, and unlimited use on all of their systems). The software
typically ‘calculates’ the necessary utilities for configuration, building and installation of systems.
The reason CalculateLinux makes excellent business software is that, it offers easy management between proprietary and open source, especially Windows and Linux clients. With a good collection of pre-configured functions, Calculate Linux 11.9 adds to its earlier capabilities.
CalculateLinux has three distros and adds fourth in new version
It offers complete client-server solution, quick installation across the business processes, seamless with varied networks, and supports rolling-release on binary updates. High interaction build supports easy administration and creation of new ISO images. Installation is supported on USB-Flash, HDD and LiveCD. Compatible with Gentoo and binary repository updates.
Until this new update, the CalculateLinux consisted of three distinguished distributions. Earlier flavors-Calculate Linux Desktop, Calculate Directory Server, and Calculate Linux Scratch.
Calculate Directory Server distro or CDS is an excellent open source software substitute for Windows NT domain controller, with very easy to and Linux clients through LDAP as well as SAMBA. It is very easy to deploy and can be up and running in a matter of few minutes. It supports LDAP, Mail, Jabber and several such other functions.
Calculate Linux Desktop KDE/GNOME distro or CLD augments Server and together provide additional features – like roaming profiles as well as centralized software.
Calculate Linux is ideal for several ranges of hardware and can be optimized for efficient work processes.
