Look for 8 Gb ram. 1 Tb hard drives aren't much more expensive than that 500 Gb you list. Don't go cheap on the power suppl y. Scuzzy has spoken highly of seasonic. They also make some that get stamped with other names, you can find which ones by searching. I would think you should look for a Cpu that is better than 2.8 ghz. I don't know where you live, but the in store price at microcenter for an i5 3750k and asrock extreme4 z77 motherboard is $189 for the Cpu and $94 for the Mb. The combo is cheaper than the 2 parts you listed and give you 3.4ghz before overclocking. A website called pcpartpicker.com lets you look up different components and their prices on different websites including newegg and amazon. Others with far more expertise than I will chime in, but I bet you can do better for not a lot more. Oh, don't know why that says Core i7 System when it is last year's i5.
