Summary: STAY AWAY from this MB if you are not going to use a discrete graphics card. Purchased this MB from another website approximately four months ago and it has given me nothing but problems. I am using it as an HTPC using the video provided by the CPU and the H55 chipset. Initially this MB worked fine except for some annoying but manageable issues with the video not initializing properly when changing TV inputs.
Summary: I teamed this board with an i3 530, Corsair ddr3 memory and an antec 310 case. Everything fits and works perfectly. Had to make some minor mods to the internals of the case to have everything fit properly but it worked out better than expected and really lovin the small form factor. Performance wise the board is a champ. The bundled software is abit buggy but I don't use it much. Updated the firmware with ease with the provided utility.
Summary: I recently installed three Gigabyte motherboards on my system builds, and I have just noticed that the DVI ports on the mobos are missing four pinholes on the right side. Therefore, if I want to connect a monitor using the DVI, I won't be able to. Fortunately, I installed graphics cards, so this is not an issue for me because I use the VGA, DVI or HDMI on the cards instead of on the mobos. Otherwise the mobos have seemed to do what they're supposed to, so far.
Summary: Using this motherboard as an open "caseless" pc. Works well with core i7 875k (using hyper tx 3 heat sink; there isn't a lot of room on the board and the h50 liquid cooler wouldn't fit), XFX 5770 in the only PCI-e x16 slot, 8gb Patriot Sector 5 G series filling the two RAM slots, Cooler Master 700w mod ps, and Win7 x64 Ultimate on Intel 80gb ssd. Tested the USB 3.0 with a Diablotek dock. Average is about 4-5 times faster than USB 2.0.
