Based on what you have told us regarding the intended use of the build - below are some pointers for you regarding your selected parts;
When choosing a case you should pick one that has a good cooling system supplied as standard, check that it is compatible with your MB and this includes the size Full ATX, Micro ATX, if your MB has a front USB 3.0 header then in order to utilize it your case will also require one as standard otherwise you would need to fit a separate USB 3.0 device which is a hassle and further expense, http://us.ncix.com/p...ec&promoid=1209
read the full specs for confirmation that it has two front USB 3.0 ports.
The following canned text covers choosing a MB, CPU and Ram;For the best and most stable performance you should where possible purchase a CPU and Ram that have been tested and approved by the motherboard manufacturer, this is referred to as the QVL ( qualified vendors list ) understand though that there are too many products released for them all to be tested so other hardware will be compatible but not proven to be.
Your CPU is overkill and you would be spending additional cash without seeing a return for it, 8 core CPUs are predominantly used by games programmers, CAD experts, 3D designers and professional video editors, if you intend taking up any of the aforementioned then fine but if not a quad core CPU is all that you will need, also please note that it is not very often that the average user will use all four cores and that includes when gaming, an alternative CPU for your consideration http://www.newegg.co...ID=3938566&SID=
Your aftermarket cooler, a very important thing I must make you aware of is that you do not need the additional heatsink and CPU fan and if you did use it you would void your CPU warranty both AMD and Intel are clear on this, see below;
This Limited Warranty shall be null and void if the AMD microprocessor which is the subject of this Limited Warranty is used with any heatsink/fan other than the one provided herewith.

damage to the Product due to external causes, including accident, problems with electrical power, abnormal electrical, mechanical or environmental conditions, usage not in accordance with product instructions, misuse, neglect, alteration, repair, improper installation, or improper testing;

16GB of Ram again is an unnecessary expense, the sweet spot for Windows 7 64-bit is 8GB and like the CPU unless you intend using the computer for anything heavy duty you will not use any more than 8GB.
The WD Black would be my first choice of HDD and then http://us.ncix.com/p...te&promoid=1209
Choose a 256-bit video card as you will get better video and gaming quality http://www.amazon.co...ASIN=B008E6XJYG
The PSU is well over and above what is required but there is no harm in that, consider though that if you can get a less expensive quality brand PSU that meets your needs and costs less than the XFX swap it as the cash saved can go towards getting a better video card http://us.ncix.com/p...ir&promoid=1373
You have not included an OS in your list of parts, what will you be installing.
Well within your budget and allows for an OS disk so if one is not needed the cost drops below $700 http://pcpartpicker.com/p/o3RSNB: Can I ask why it is that you are opposed to an Intel CPU.
