The Plug-N-Run E1 offers Core 2 Duo processors at 2.16 and 1.5 GHz. CPU performance is augmented with the E7520 and 6300ESB I/O controllers. These server class components provide a FSB at 667 MHz, support for dual channel access to up to 4GB of ECC memory, 2-X8 and 1-X4 lanes of PCI Express, and 2 Serial ATA channels with RAID support. In addition to these major throughput features, the E1 includes Gigabit Ethernet, 8 USB ports, and much more.

This substantial performance and throughput engine is packaged on the standard COM Express Extended 155mm x 110mm (6.1in x 4.3in) form factor. PFU Systems is one of the originators of the PICMG COM Express standard and the only PICMG member that provides the full-scale extended form factor.
