The exploded system shot shows a beefy heatsink devoid of fans. ECS doesn't specify which processor is under the hood, but it does say the machine offers "64-bit dual-core performance up to 2.25 GHz." The only Bay Trail SoC matching that description is the Celeron N2808.
Versions of the Liva X will be available with 2-4GB of RAM and 32-64GB of eMMC flash. Additional storage can be added via the internal mSATA slot, but there's no room for a mechanical drive.
A trio of USB ports provides peripheral connectivity, while HDMI and VGA ports cover video output. Wireless options include 802.11n Wi-Fi and Bluetooth 4.0. Gigabit Ethernet is also included, giving the Liva intriguing potential as a client for Steam's in-home game streaming.
ECS's current Liva mini PCs are pretty affordable, so I'd expect the X variant to follow suit. The apparent lack of a quad-core version is disappointing, though. I'd happily pay a little extra—and live with a slightly larger chassis and heatsink—to get a Bay Trail quad like the Celeron N2940.
