Hello Tom's Hardware forum members. I'm looking to build a gaming computer on a $800-$850 price range . I wish to purchase these parts from newegg if possible. Please see below for a list of parts within, and if possible please make sure I haven't messed up . Thank you for looking this over, and I hope you might be able to improve my build .

Motherboard-GIGABYTE GA-Z77-D3H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard($125)
Looks pretty quality to me, good to see someone put together a rig for their purposes instead of their pride (although I am likely guilty of that lol). I don't hear great things about the green/blue WD lines, I think the samsung Spinpoint is a pretty good base drive, most would recommend the WD Black as a "top of the line" desktop HDD (for its price point and such). The video card is the only other thing I am not sure on, hopefully someone else can chime on on that, but your PSU is good, MOBO looks good, CPU is good, RAM is good, and I don't think you can go wrong with that case. I think your Wifi is an external USB solution just an FYI (which is probably fine, you probably don't have tons of PCI to spare).
Unfortunately, that Corsair V2 Builder was made by CWT, not Seasonic, and uses some inferior Samxon capacitors known to experience early failure. It tests well when new, but may not hold up. This information comes from a HardwareSecrets thread, then proceeds to the badcaps.org forums.
If gaming at 1920x1080 is your focus, you would benefit from a stronger graphics card, like a HD7850 or HD7870. If your resolution is 1440x900 or lower, you might be happy with the HD7770.
Check out Rosewill's gaming cases, such as the LINE, BLACKHAWK, or R5. They come with more fans than the CM, so you won't need to buy more.
I also prefer the WD Black drives, as they're the only ones to retain a five year warranty since the floods. They're also fast. Samsung has cut the Spinpoint's warranty down to a miserable one year, so I will no longer buy them.
Since you're getting a locked CPU, you can save money on the mobo by getting a H77 board. If you're planning on a CPU upgrade at some point to an unlocked chip like the i5-3570K, then start with an i3 now. Either of those changes would likely let you improve your graphics card without spending more.
