The Memory Heatsinks are more for looks then anything.
But yes, the blower thing is awesome. I've been wanting one for awhile because they suck hot air out like crazy. Which helps overall PC temperatures go down. And the VGA cooler that I'm getting is really sweet looking. It's got a massive heatsink pratically wrapped around the entire thing, and then has 3 fans blowing down on it. I'm positive that this thing will keep a video card cooler then a Zalman would.
But yes, I want to make my computer an official badass! Next time I go to the LAN parties, everyone will be wanting to see what I got. Plus with all the cooling in there, I should be able to overclock without any problems!
