Why do I need a better motherboard to overclock?

Hi
I have an i5 3570K and a GA-B75M-D3H motherboard.
I originally bought these particular components to make a hackintosh (the K has supported HD4000 graphics)
I'm aware that because it's a K version I can overclock it, but apparently it's not possible on my motherboard because its not a Z87? or a Z77? Or something like that.
I'm not too fussed about overclocking I just wanted to know why it's not possible on my motherboard?
Thanks

The z series chipsets are required for overclocking. No way arround it. To overclock you need a K-sku CPU, a z-series chipset, and an aftermarket cooler that can handle the extra heat from the CPU. This typically ends up being $30 extra for the CPU, $20-150 extra for the motherboard, and $30-80 extra for the cooler. You have to pay to play it seems.

Because that motherboard is more for a business class PC so it doesn't have all the bells and whistles.
With it you can't adjust CPU voltages or multipliers which are critical in overclocking. Also you don't have all the proper heatsinks that would come standard on an enthusiast level mobo to handle the extra power. If you were somehow able to hack that board and overclock it, it would likely melt.

Also, certain motherboards are better at handling voltage, and thus some boards can use less voltage (my old Asus P8Z77-V LK needed 1.35V to have my 3570K at 4.5 GHz stable and my ASRock Z77 OC Formula needs 1.3V). This is not so for Haswell, if I'm correct, because the VRM is on the CPU die, not the motherboard.
