My PC build

Hi guys, I've decided to build a high end gaming PC and these are the specs:

CPU = i5-3570K
CPU Cooler = Corsair H80
Motherboard = Asrock Z77 Extreme 4
GPU = Gigabyte GTX670 2GB OC Windforce DDR5
RAM = G-Skill RipJawX 1600MHz CL9
HDD = WD Caviar Black 1TB
SSD = Samsung 830 128GB
Case = NZXT Phantom 410
DVD = Just any one will do
PSU=Corsair HX750


Also gonna buy 2 Corsair SP120 fans to put on the H80 for a push/pull configuration


Im probably gonna build it at the end of this month/year, is there any place in singapore that I can build this at a good price. Also any thoughts of the above specs?
