Main points I need help with is the case selection and if the rest of the parts will work together ok. Also if anyone has the above graphics cards, can you comment if they are indeed cooler and/or quieter than the reference designs? RAM voltage and the mobo should be fine, will PSU suffice (will have 4-5 HDDs and a SoundBlaster X-Fi card in the build)? Keep in mind I will only overclock later down the track when the set up can't handle games I throw at it.
The psu will actually be overkill. Even a 650-700w will be plenty for those hdd's and that gpu. To me cases always come down to personal preference. If you like the way it looks,if it has the feature and adequate cooling that you need, you should go with the one you like =D
According to Asus' PSU wattage calculator, minimum is 750W but according to Outer Vision Extreme, it's 696W. I thought getting a 850W would be to err on the safe side and give me a bit of headroom when I do eventually OC the machine.
Also $100 is a lot of extra cash, I like both and it would ultimately come down to performance. So anyone with experiences of either (both ideally) willing to share, would be fantastic
