ECS places both an IEEE 1394b and 1394a ports on the rear I/O along with four USB 2.0 ports. In terms of connectivity, the rear I/O supports all the standard interconnects, except for a printer port. The printer port is included as a bracket along with the ECS PN1 SLI2 Extreme. There are also three USB 2.0 and one IEEE 1394a internal headers available for expansion brackets.
