Looks like the first C7-based EPIA from VIA has been announced.
Press release...VIA Launches Most Powerful EPIA Mainboard Ever; First to Feature VIA C7 Processorhttp://www.via.com.tw/en/resources/pressroom/2006_archive/pr060313EPIA-EN.jsp

Its available this month in limited numbers. (production is just starting, I guess).
I'm really tempted by the 1.2Ghz fanless one!
I've already got an older (fan cooled) 1Ghz C3 based one...This is faster and consumes less power. (I like the idea of fanless. Silence IS golden!)
