Paranoia X200

The Paranoia X200 is a modified Thinkpad X200 with Libreboot and Parabola GNU/Linux preinstalled. Libreboot is a free (as in freedom) BIOS or UEFI replacement, initialising the hardware and booting your operating system. The Paranoia X200 also contains a Linux-Libre kernel and a BusyBox shell stored in the flash memory where Libreboot is installed, which can be used as a rescue system. The keyboard layout is German, the plug of the power adapter fits in both German and French outlets. The size harddisk is 160 GB, RAM is 4GB and can be upgraded to 8GB. The Intel WIFI card is replaced with an Atheros AR2985, which works out of the box with free software.

The Paranoia X200 uses an Intel Core 2 Duo processor which has enough power to do most development tasks. Because Libreboot allows the use of all the graphics memory Blender will probably run with the best performance that a libre-friendly computer can offer. Other use cases include music production (Parabola contains a collection of packages commonly used in a GNU/Linux audio workstation) and video editing using avidemux. It can also run many games including the Battle for Wesnoth, SuperTux and SuperTuxKart and MineTest. In the future there will be also variants with GuixSD and Trisquel.
