The first microATX board in this preview is the Gigabyte A75M-UD2H. Clad in the blue and white shades that Gigabyte has been using for many generations, this board basically comes with less expansion options than the ASRock and ASUS. The crucial elements are still there: five SATA 6Gbps ports and one eSATA port, four USB 3.0 ports (two via headers) and there's even a pair of PCIe 2.0 x16 slots.
Despite its limited space, Gigabyte manages to pack in a FireWire controller from VIA and more impressively, has the full complement of display outputs (VGA, DVI, HDMI, DisplayPort) at the rear panel. There are six USB ports at the rear in total, two of which are USB 3.0 ports. Although there are two PCIe 2.0 x16 slots (with the second having x4 bandwidth), Gigabyte says nothing about CrossFireX support in the manual and while we await clarification from Gigabyte, it's quite likely that this is not supported.
The board itself feels slightly heavier than it looks, aided no doubt by Gigabyte's Ultra Durable 3 feature that calls for more copper content in the PCB. Like the ASUS, our slight peeve is that onboard buttons are missing. Gigabyte is also using a familiar Award BIOS that 'appears' to be non-UEFI, but they would say otherwise anyway with their Hybrid EFI implementation that provides the technical aspects of a UEFI, but not the visual aspect.
Overall, the smaller form factor has not adversely affected the layout on this board, which is pretty neat despite the number of features present.
