Although it wouldn't make a huge difference, I recommend getting a Samsung F3 500gb, it runs a bigger platter size so you'll get a faster boot on Win7 (or whatever your OS is). Plus F3's are realy beasts.
As for your disk-drive, any will do. Lite-On is good, Asus is good, Sony makes some of that price to as well as LG. So anything will do.
Your memory very bad decision, not to say that Corsair is a bad memory company. But that ram is a single channel and will not perform as well as Dual channel memory. the Cas Latency is also really high for that kind of ram and although you won't notice it that much. During things like Archiving (Winzip) or things like that you'll see a difference. So I recommend going with this. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
it's 10$ more but it's a faster speed of 1600 and lower Cas Latency (7) and mushkin is a real solid company. Plus it's dual channel.
As for power, Vibhas is right, you'll only need like 400 or 450. I mean this is good enough for what your doing. It's 45$ but only 34$ after the MIR and Corsair really honors that kind of stuff.
That's all for my suggestions, as for case. IMO go with a Cooler Master case. Oh and, I wouldn't go with that mobo, CompUSA is more like stealing your money for that price. At 70$ plus a MAYBE rebate. You could get a way better mobo than that piece of crap.
I suggest going on Newegg. Not CompUSA, putting a little more into your mobo budget goes a far way on future proofing, and I'm pretty sure you want to future proof. Here is an ATX mobo with USB 3 slots and Sata 6 slots. Way better choice.
