lol, i have the same mobo and case... with my personal experience it has been a sweet system. ur case link is wrong though, it goes to the mobo u picked out, but its all good. i havn't heard too much about that processor. You may get a better lifespan (in terms of quality) with a dual core processor... don't get me wrong though, these are all great parts.
Ram - you may want to up the speed of it. i wish i did because im going to have to buy some different kind later if i want to get it faster. Only do this if ur going to oc it though.
psu - i absolutally love my psu but its got the SLI sticker on it jacking the price up a few bucks. With psu's, its really the more u spend, the better it is. If i were you i wouldn't spend less than 75 dollars on one. Also, since ur running a few gigs of memory as well as the fx-57, u need some high wattage psu's. Anything over 450 is good, over 600 is overkill (correct me if i am wrong though).
cooling - simply grab a zelman beast - http://www.newegg.com/Product/Produc...2E16835118115.
that should do the trick, because the case u picked out has AMAZING cooling... i can't believe how much air gets pushed out the back of that thing. Also, the case has dust screens everywhere dust can get it, so it stays at the same quality of air cirulation throughout time. Also, this eliminates the need for cleaning it every month or so!! btw, i also disagree with water cooling... its so... weird to think about putting a "threat" in your system...
hard drive - i totally agree with you in the sense of getting a rapter... glad to see that. i would definatelly say a 150gb or 74gb raptor AS WELL AS "storage" hard drive about 200+gb. This way, u put ur programs and such on the fast drive, and put larger files such as movies, pictures, mpeg layer-3 files on it that aren't getting accessed all the time. The hard drive is usually the bottleneck of every system. I totally can't wait till i get a faster one and let my processor "fly".
Looks like a great system with no major errors... GOOD LUCK!!
