Nice specs but wouldnt you be better off with faster ram seeing as your mobo and cpu are 1333fsb ?
The Coolermasters are nice cases but I would rather have space for more hard drives so that I could add hard drive coolers to them, that arrangement would only enable you to have one cooler fitted to one drive if you had 2 drives in the bottom cage, no room for a 3rd drive so youd have to use the internal 3.5 above the main cage which again wouldnt have room for a hard drive cooler if you wanted 3 drives. I have 4 in mine at the moment.
The power supply is a good one but only has a 4 pin CPU power connector, some CPUs now want an 8 pin one so that it takes 4 pins off each 12v rail.
I had to get a special adaptor to convert my 4 pin to the 8 pin type so would always look for a 2 x 4 or 8 pin PSU in future.
