Looks pretty good but as an owner of the Graphite 600T, I will tell you - it's a great case but it is BIG. Really big. Plus the fans are a bit of a hassle to get working - you'll need a couple of Y fan connectors to connect them to your PSU instead of your motherboard.
If you wanted to stick with Corsair try the Carbide 400R instead - it's about half the price and still an excellent case - well worth buying.
the i5-2500k is a good alrounder for a CPU. i would go for somthing along thes lines of a "p8z68 mother board from asus" i have the Corsair graphite 600t and i can tell you its like a fridge in there! well worth the extra cash..... (tho i paid £220 for mine in the uk about 3 weeks ago and i can tell you i would of rather paid $170 lol!....
can you go for a small and cheeper hard drive? just with prices so high your better off buying a smaller hardrive (250/500gb) and investing into a solid state drive.... with all these floods in thailand your better waiting till around march for when they SHOULD start comming back down in price again
