Well the biggest issue I see is you picked an H67 motherboard with the i5 2500k. The 2500K is unlocked for overclocking, but the H67 chipset doesn't allow overclocking. You should buy either P67 or Z68, ideally get one with 8x/8x SLI/Crossfire PCIe support (some are 16x/4x which is worse).
Otherwise I like it, though the 600W PSU won't allow you a lot of headroom - for example you can't crossfire 6950s in the future without upgrading it. For the system as is, it's fine.
Yeah, i didnt want to overclock, but on that website they don't have a 2500 non K although the one there has a free game and is therefore more expensive and i dont what that
