Pros: $90 for this enthusiast grade micro Z77 is amazing. Why is it enthusiast grade? Well, they didn't really lock out any BIOS features. It's a full-fledged overclocking board complete with 100% solid state capacitors, digital PWM, ASRock's unique BIOS features, and their cool software suite.
Cons: Nothing really. I now know that I'll never do an mATX build again... such a small board is only inconvenient for installation, and there's very few fan headers. My GTX 680 FTW LE covers the four SATA 2 ports, it didn't look like they could be used. Luckily for me, I only use SATA 3.
