thanks   cant wait to build it! I'll definitely pick up a 212 EVO.

550W is overkill for your system. Drop down to 430-450W and use the difference to get a Radeon 7770 & CPU Cooler. The same thing can be said for the case.

You picked some quality components. Like sonicers said, you should probably get an EVO 212. You can also get away with a smaller PSU, but I wouldn't go any lower than 500 watts if you are gonna overclock your CPU and possibly your GPU. Look at some of these alternatives.

Price breakdown by merchant: http://pcpartpicker.com/ca/p/mm42/by_merchant/
Benchmarks: http://pcpartpicker.com/ca/p/mm42/benchmarks/

CPU: AMD Phenom II X4 965 Black 3.4GHz Quad-Core Processor ($89.79 @ DirectCanada)
This CPU is only $10 more and it overclocks better.

CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler ($28.91 @ DirectCanada)
This is required if you want to overclock. The stock fans on the phenom series are terrible and are really loud and inefficient.

Storage: Western Digital Caviar Blue 750GB 3.5" 7200RPM Internal Hard Drive ($58.82 @ Amazon Canada)
This HDD is basically the same price, and it has more capacity and a larger cache.

Video Card: MSI Radeon HD 7770 GHz Edition 1GB Video Card ($94.99 @ NCIX)
This is an obviously superior graphics card and it is cheaper after the rebate!

Case: Zalman Z9 Plus ATX Mid Tower Case ($39.99 @ NCIX)
Cases are purely what you want and they are hard to recommend on an individual basis, I included this one because it comes with more case fans for a better ventilation system.

Power Supply: Thermaltake TR2 500W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply ($45.99 @ Canada Computers)
You picked a quality PSU and there is nothing wrong with it. I included this one because it is sufficient for what you want, and its $10 less.

Total: $358.49
(Prices include shipping, taxes, and discounts when available.)

If you have any questions, just ask.

You forgot a motherboard. I'm not harping, I'd fill it in but I'm not up to date with AMD's motherboards.

To be honest, I prefer buying from one site, not multiple. I already know of directcanada however I decided not to buy from then since they have a very LIMITED selection on am3-am3+ mobos, and the ones that i found were overpriced.

I decided to switch to a Zalman Z9 plus case, and I'll stick to my 550watt power supply. I think this build is great for the price  

Sounds good. I didn't include a mobo because the OP already had a good one chosen.
