VIA EPIA is a series of mini-ITX
Mini-ITX
Mini-ITX is a 17 x 17 cm low-power motherboard form factor developed by VIA Technologies in 2001. Mini-ITX is slightly smaller than microATX. Mini-ITX boards can often be passively cooled due to their low power consumption architecture, which makes them useful for home theater PC systems,...

E Fanless configuration
G RoHS-compliant
L Configured with Gigabit
Gigabit Ethernet
Gigabit Ethernet is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second , as defined by the IEEE 802.3-2008 standard. It came into use beginning in 1999, gradually supplanting Fast Ethernet in wired local networks where it performed...

Criticism

Although VIA EPIA motherboards are very efficient in terms of space, they are sometimes criticized for being too expensive for the processing power that they provide. It has been commented that other manufacturers, such as PCChips and ASUS

, provide more affordable solutions based on the same technologies, namely VIA's low-power processors.http://undeadly.org/cgi?action=article&sid=20061115152127&pid=42

Via has failed to provide support for some features it sells EPIA boards based on. For example, although the chipsets support hardware H.264 decoding, no driver for Windows is available. In fact, only an outdated version of mplayer
