Dont get 6GB of ram, only get 4 for a non i7 build. The antec 900 should have plenty of cooling even without the add on fan, i would also swap out the ecogreen drive for the spinpoint for $5 more, or the caviar black for a bit more. If you use the template shown here we can probably help you find a better build for your needs http://www.tomshardware.com/forum/261222-31-build-advic...
the memory is triple channel, and thanks for the help with the case. would it still have enough if i oc the video card. the reason im getting 6 is because it costs about the same as 4 so i figured what the heck. i dont plan to upgrade for as long as possible
Get 4 gb with CL 7, im guess that is a fairly high latency dual channel kit, CL9 likely, you dont get a benefit above 4 GB for most things, and you will actually take a performance hit because it will be running in single channel mode instead of dual channel mode.
The majority of the heat from your graphics card gets exhausted out the back of the case by the cooler on the GPU and the antec 900 has a ton of cool air being pulled into the case by the front fans.
Link to your parts because im sure there are better deals on some of them, if you are buying from newegg you can get combos on a bunch of those.
CL is cas latency, it refers to how many clock cycles it takes for a block of ram to get accessed, lower numbers are better, but often they are achieved by boosting the voltage. Low latency at low voltages indicates higher quality chips than those that have to raise the voltages.
take a look at their specifications to see their full set of timings, a few recent reviews by the toms staff has shown that the performance difference between CL7 and CL9 at 1333MHz is greater than the difference between 1066MHz and 1600MHz ram which is only about 2%. Even if you get the cheapest ram you can you probably wont see too much of a difference between it and using super expensive ram.
I advise against the open box one because all you get is the board, you dont get the cables that it shows in the picture, or the manual and for a first build that manual is invaluable. This board will only cost you $22 more after MIR. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
