Simulations and Gaming PC.

Two fans are usually quieter than 1 because they don't need to spin as fast to move the same amount of air.

Makes sense and thanks for the links. I'll update the build.

A lot has changed in last two weeks. Simulations will now mostly run in private VMWare cloud, so that will spare my machine mostly for development work and gaming. I already ordered case and PSU from scan today. Free delivery thanks to Hexus!

This is the most recent build I am going for. Unless you guys find something absurdly wrong with it, I will place order sometime tomorrow.
