If you're looking to save a few dollars, it can certainly be left off and you can just use the stock Intel cooler that comes included. But for the price, it's a good value. While we mostly wanted it to improve the look of the build through the window, it will also typically run a bit more quietly than the stock cooler.
Oh gotcha! Thank you. I went and tweaked some parts from this build to have that white themed going and do you think i should keep the motherboard or find a cheaper one that's around the motherboard from this list?
