You're not going to hit that unless you use a custom watercooling setup - most i5-3570k's hit 4.3 to 4.5 on air, and that's with a good motherboard and large cooler.
That being said, you can achieve that kind of overclock (~4.4GHz) on a mini-ITX with a low-profile cooler, but the temps will be slightly higher than on big air.
I don't know much about micro ATX motherboards, but the only two mini ITX boards that'll get you good overclocks are the AsRock z77e-itx and the Asus p8z77-i deluxe. I bought the AsRock before the Asus came out, and while it easily got my 3570k to 4.4GHz with a 140mm downdraft cooler, I HIGHLY recommend the Asus for a couple reasons. First, it's got a special board filled with power VRMs, which is good for overclocking if you don't have as good of a chip as I got, and second, it's got a better layout - on the AsRock you're limited as to cooler choice because the CPU socket is too close to the PCIe slot.
