The Lian Li V series is a great case. It is expensive but not over priced; you get exactly what you pay for. If you don't have a lot of drives however take a look at the PC-600, I actually think it looks better then the V1000. The only downside is the limitation of low profile heatsinks but the CNPS-7xxx will fit without problems.
I would go with Corsair, Mushkin, Kingston, or Crucial for the RAM, and consider Asus, Intel or Gigabyte for the motherboard over Asus.
Lastly the Seasonic S12 is great choice but the 330 or 380 watt variant will be plenty for your specs.
