ddr2 1066mhz ram & GA-G31M-ES2L

i am new to the boards. i have been looking around here as i have recently decided to attempt my own custom mini clone. i am thinking of putting an intel e5200 on a gigabyte GA-G31M-ES2L motherboard and overclocking it to 3.3GHz. the case has a 270 watt psu, but i've heard that these chips don't use much juice and i am skipping the optical drive. when i get the money, i would install a raid controller and two raptor hd. i have a parts list, click the parts numbers for the listings:

$49 case; N82E16811121027
$50 motherboard*: G452-0008
$73 CPU; N82E16819116072
$24 RAM; N82E16820161042
$60 GPU; N82E16814150353
$42 HD; N82E16822136075
$10 firewire; N82E16815124057
*listing from compusa.com; all other listings are from newegg.com.

what i am wondering is if anybody has tried these parts together. i've seen lots of threads attesting to overclocking similar chipsets, but nothing specifically about the ram. the specs on the motherboard say that it overclocks to 1066mhz. so does that mean that i can run ddr2 1066 ram, or do i have to stick with 800 because of a limitation on the front side bus. i'm a total n00b to this stuff, so fire away.

i have specific needs and am trying to really keep down the budget, so please keep comments relevant to this parts list unless you are sure that they are incompatible. i have a superdrive in my old sawtooth and thought that i could use that through target disc as my optical drive and for additional file storage over firewire.

270w is not going to be enough for that system. The video card you selected says it needs 350w to get it done (although these are bloated figures, they are somewhat close).

This memory will be much better I think. They do the same timings and at a lower voltage. Also, your mobo only suports 1066 ram through overclocking. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231084
