Here's a full opinion. If I had your budget this is what I would get:
Note: I've used pccasegear which seems to be commonly used by guys over there.
I've put in an
air cooler rather than the H80. Why? Well the NH-D14 is both cheaper and better at cooling. If you want to upgrade to an H100/custom watercooling then that is a different setup which is both more expensive and better performing. The problem with going under water is that the case you've eyed up isn't ideal with 180m fans in the bottom.
It would take some modding. I tend to feel that the
case is a bit overpriced and the features are awkward but since cases are the most subjective part of a build it's not really my place to tell you yes or no.
I've knocked down the
mobo to something that performs exceptionally but for a much better price. It is still blue, although a slightly different shade. I've also changed the RAM and tried to fit the colour - feel free to change this. Any RAM which is 1600MHz and 2x4gb sticks is just fine but you'll need it to be low profile with a large air cooler.
Upgraded the
HDD to a WD green which is a better product overall. Yes it is slower but you have a nice big SSD for running anything that needs speed from. Storage drives are just for things like films/music/pictures and documents which require very little speed from an HDD. The green is very reliable and energy efficient.
Upgraded the
GPU to a 670 with an awesome 3rd party cooler. In fact I managed to fit in
two for your budget which is mental for single screen 1080p gaming. You could just get 1 and drop your budget by $420. The 670 is better because it has better bus bandwidth which can be noticeable. If the 660 makes 670 speeds then that's great but the 670 will rival a 680 when
both are overclocked. This 670 is only $70 more than the msi PE 660ti but the 670 is $155 less than a comparable 680 (with 3rd party cooler) which it will stand toe to toe with. That's why the 670 has the best performance/money and why we recommend them. With your budget there really isn't an excuse! As an alternative I would suggest a 7950 with 3rd party cooler.
Something like this is both cheaper than the 660ti and will overclock further and will fight a 680 at stock if you want it too.
As it stands you have $165 to spend on
lights and PSU cables.
You might notice that everything is black and blue still. Well technically the mobo is dark brown and blue but I've got one and I don't notice the colour unless I'm looking closely at it.
