Form Factor

The CRB is designed to fit into an ATX-form-factor chassis.
mechanical form factor for the CRB. Dimensions are given in inches. The outer
dimensions are 10.75 inches by 12 inches, which means that the CRB is actually about
an inch longer in depth measuring from the back panel across. Location of the I/O
connectors and mounting holes correlate with the ATX specification.
