@ ciiiz - if you get the NH D-14, you'll find height clearance issues when you have ram installed.
Getting the CooLit system is a waste of money...its just a bragging right material - but it doesn't get the job done. Sticking to air cooling would be the best idea - pick up a CoolerMaster Hyper 212+, its good on the wallet, good to work with OC's and easy to setup.
IF your really hell bent on gettin a closed loop WC system - by all means get the Corsair H50 CWCH50-1 - tests/reviews showed that the H50 is far superior to the coolit even while having two fans across the rad in push/pull config
get a X4 955 BE, the X4 outperforms the X6 in gaming.
as a matter of fact you'll only need a triple core x3 to run most games as a test on Tom's showed - you never need more than 3cores for gaming - if your using multi-threaded application, the x4~x6 will come in handy...
note before # you can get an i5-750/P55 mobo/4~8GB 1600 DDR3 Ram/GTX 460/470 if this a gaming only PC. The hyper can also OC the i5- close to 4.0GHz
@Mr Pizza, @wortwortwort and @Lutfij thanks so much for suggesting the NH D-14. I've read and watched some reviews of this beast and I'm sold this thing is amazing. installed it right away
@dknutson, hey thanks for the reply, but I think u didn't notice that I have a 300$ monitor in this build.
@Lutfij, thanks so much for the great info. You are absolutely right about the height issue of the RAM, the ones I had (the G.Skill's) could cause problems there. So, I installed the Mushkin silverline u pointed out. One thing I noticed about them though, they are DDR3 1333 while the G.Skill's are DDR3 1600. I'm a RAM noobie so should I worry about this?
I didn't forget the keyboard I left it out on purpose
