OpenBrick is a small, light and silent open platform optimized for Open Source / Free Software solutions (firewall, micro-server, PABX, thin client, multimedia...). It is available for 300 to 400 EUR. It is distributed by a network of Open Source / Free Software companies who are joining through the OpenBrick Foundation to optimize it for GNU/Linux and FreeBSD, adapt it to new applications and improve its specifications.
