Seriously try getting help from a pro you don't want to be buying all this stuff then fuck it all up.

 

No, do not get a 'pro' to help you. They will charge you absurd amounts for the simplest of tasks. Also, why did you bump this? It's 3 days old...

@OP if you still need help, add my msn in sig.

 

Everything looks pretty good as is, the only thing I would change is the mainboard, I recommend getting something with 4 ram slots so you can upgrade when you want later, I know you already getting 4gig but with some of the games that are coming out Crysis 2 & Bioshock Infinity i have a feeling you will need more. Have a look at Gigabyte or ASUS from that website you showed, also your current mainboard has 1 PCI-E I reckon you should get a board with 2 just in-case you want to xfire or something.

 

Looks very nice. But, you really don't need such an expensive power supply.
