If you buy an aftermarket cooler will not interfere with the tall memory hetasink.
From the RAM what you choosed buy Corsair is at 1.5V , this is the standard voltage for socket 1155.

thanks for the reply

dabs are currently offering a bundle, which i am thinking of buying: http://www.dabs.com/products/asus-intel-performance-bundle--includes-p8z68-v-lx-motherboard--intel-core-i5-2500k---8gb-ddr3--7VJG.html?src=3

however this comes with the patriot RAM, what is the difference between using corsair and patriot ram?

The voltage and Patriot have higher frequency 1866Mhz and Corsair 1600Mhz.
That bundle looks good.

okay does the higher frequency mean its faster? just want to know if im missing anything from not buying the corsair

I'm gonna agree w/ sosofm except for the part about 1.5V....I'll take 1,5 or even 1.35 when its a good deal but I have no qualms about using 1.65 volts .... after all no one is voiding warrantees if ya use it.

Sandy Bridge does not demand only 1.5v modules, it will be perfectly happy with 1.65v modules too. If someone tries to tell you that you must have 1.5v modules, then they are either trying to sell them to you, or they have been reading misinformation, or both! Another point to consider here, is that in your BIOS, if you head to the memory voltage setting, and enter 1.5v, the text will remain white/grey, if you enter 1.65v, it will turn yellow, and it isn't until 1.73v that it turns red, so at the moment, I'd rest assured that 1.65v modules are OK to use, and I have had this confirmed by Asus, Gigabyte and Corsair

thanks for that, so the patriot should work just as well then?

what does the higher frequency/voltage mean though?
