Just some suggestions on what I would do...
1 optical drive is plenty, don't really know why you would ever need two in today's day and age... Back in the day people had two when cd burners first came out.. One to read, one to burn. Upgrade to a blu-Ray instead of two DVD drives
Corsair makes excellent power supplies. 850 watts might be slightly overkill for your system. A 650 watt power supply will power 99% of all 1 gfx cards systems on the planet. More power won't hurt tho. Also I've heard modular psu's are slightly less reliable, but I think that they have changed and are much better now, if not just as good as a traditional psu.
that case looks nice. Any Antec, coolermaster, Lian-li, thermaltake or corsair case should get the job done. As far as the cooling I don't think an aftermarket cooler is always needed but again it can't hurt. Water cooling, as mentioned earlier, is only needed for serious enthusiasts and overclockers
good luck with your build
