This is the 2nd series of EPIAs to use the new C7 chip. The official page can be found here. http://www.via.com.tw/en/products/mainboards/motherboards.jsp?motherboard_id=400 This one comes in 1Ghz and 1.3Ghz models. (Where as the EN-series came in 1.2Ghz and 1.5Ghz models). From what I gather, the CN-series uses regular 10/100Mbit LAN, there's no Firewire, and less onboard connectors than the EN-series. The physical layout is slightly different as well.
