[ros-users] Hardware requirements for ROS core components

Hello!
What are the minimal requirements for the computer on which we plan run the ROS? We have a board AT91SAM9260 based on 200 MHz ARM and installed Linux. Is it enough to read data from the CAN bus and transfer them to a remote computer over a Wi-Fi if we plan to use the ROS core components?
Are the some recomendations to choose a hardware for ROS?
Thanks.
