Gigabyte A75N-USB3: Mini-ITX Motherboard for AMD Llano

Gigabyte is preparing a new Mini-ITX motherboard with AMD socket A75 Llano, the GA-A75N-USB3. It will be an alternative somewhat less complete than the Zotac A75-ITX WiFi, but not necessarily less interesting. If the Zotac model offers dual output Ethernet, WiFi n, and more USB 3.0 ports compared to the Gigabyte model, the A75N-USB3 will be more affordable.

First recall that most of the connectors you would expect on a multimedia oriented Mini-ITX  motherboard is present, namely an HDMI 1.4a (plus one DVI), optical S/PDIF, Ethernet Gigabit, eSATA and USB 3.0 ports (4 in number). Note however that Gigabyte does not offer USB 3.0 internal, and is confined to an 5.1 analog sound. 

The side of the PCB is still slightly less aimed than the Zotac, there are therefore two locations DDR3 memory, 4 SATA ports 6 and a socket FM1 close enough to the port PCIe 16x, which could be problematic if you install an expansion card and a big cooler for the processor.

But the motherboard The map could be interesting because it should be started at about €100 in Europe soon, a rate from 20 to 30 € cheaper than the Zotac model.
