^^there's my build. I'm pretty happy with it, except for one thing. The case.
I want to upgrade a little with case. Anything within the prices of $90~$130 will be fine. I want something with great airflow (mid tower but nearly full), comes with many fans, looks mildly awesome and of course easy setup. I've got my eyes on a few.
-CoolerMaster HAF 912
-Coolermaster RC-692 Advanced II
-Thermaltake Armor+ MX (this one is a little over but shouldn't hurt the budget too much)
-Thermaltake level 10 GT (nah jk)
i have an antec 900 mk2 and its a good case. bit of a dust magnet but if you keep it clean its well worth the price. the front fans are a little noisy at full but you can turn them down with the on board fan controllers
the haf is also a good case although its fans are slightly noisy
Keep in mind that since you have a Sandy Bridge CPU you need to get RAM with voltages below 1.58v. That is because the Sandy Bridge CPU's Integrated Memory Controller doesn't handle high memory voltages well. There was a story shortly after the Sandy Bridge launch chronicling an alarming number of Sandy Bridge chips dying from excessive CPU voltage, but also dying from RAM voltages that were too high.
With that said your RAM voltages have to be fairly high in order to cause problems, but to be safe I'd stick with modules that can run below the 1.58v level that has been mentioned as "safe".
CoolerMaster HAF 912 Advanced - $119.00 http://www.pccasegear.com/index.php?main_page=product_i...
I never recommend this case in North America because it's overpriced and featureless.Comes with 1x120mm fan and that's it = no window or USB 3.0
Wow they've loaded it up for your market which makes it a very good case.
2X200mm fans/1x120mm/Window/2xUSB 3.0
Antec 902 Nine-Hundred is a really good case however i couldn't source one for you.
My guess is they are waiting for 902v3 stock which is an improved version adding a cpu cut-out,ssd tray,and Usb 3.0.
Rock solid case high quality construction compared to the CM's which use more plastic.
I use one for my main rig which runs cool and quieter then my 690II.
Any one of these cases would be very suitable for your build.
