The Z68 Pro3-M from ASRock is a nice alternative to the standard size mottherboard. Unlike the H67 chipset its offers all the power and features of the Pro3 which is its bigger brother. Many of us are not always in need of having a mid size or larger case when a small form factor would work as well. But we still require the power that a standard ATX offer. The Pro3-M gives you that. A full length PCIe slot, four DIMM slots and all the new features that comes with the Z68 chipset like Intel's Smart Response and Lucid's Virtu.
Another reason we prefer the Z68 chipset offer the H67 is because of the fact overclocking is not eliminated from the system. With the Z68 chipset you do not have to rely on Intel Speedstep to get an CPU boost of performance. You can go into the BIOS or use the AXTU application to achieve it yourself.
The ASRock Z68 Pro3-M goes for about $115 at most respectable retailers.
