Pricey case, but dang does that have some cable management options lol. Even a 750/850W PSU would be plenty for SLI 560s. For this kind of budget you might even want to wait until the Sandy Bridge-Es come out, only guessing budget based on all of your parts have tons of better value options.
What is the budget range? What do you primarily use the PC for?
Its a really nice build, mostly. To me it seems like you've gone for almost all of the highest priced options, other than the graphics cards.
If the build is for gaming you could save yourself ALOT of money by:
Swapping out 800d for 650d (case)
Swapping out i7-2600k for i5-2500k
Swapping out 1200w PSU for 850w-1000w PSU
Swapping out motherboard for one about half the price (not sure why you've gone for E-ATX but standard ATX would be fine for SLI build)
Maybe even scrap the sound card
With all the money saved above you could be running SLI GTX 580s which would provide MUCH MUCH better gaming performance than SLI 560's
EDIT: I also dont see any RAM/Optical Drive/HDD listed - although maybe you already have these.
A budget would also be useful + what the system will be used for
yah most is pricey stuff.. the tax 1200 is a given for future...it seems new egg is outrageous with pricing lately now ncix is like 200 cheeper for just case and power supply.. I'm thinking level 10 gt but the cable management might be a problem.. the 560 are up in the air i want something better..i could run try or quad docent matter pci.30 is a consideration
