I wanted to know if it was compatible, if the ram is good and if I had to buy a low profile ram because that zalman cooler is huge.
Anything missing? I have the case the GPU and the PSU
That particular cooler shouldn't pose any problems with the ram. Since you only have two sticks, even if there was an issue you could populate the outer two slots with no problem. Having said that Corsair does offer low profile Vengeance that are just as good.
However I'm wondering why you chose such an outdated cooler. There are many superior coolers out there in that price range, such as the Coolermaster hyper 212+.
