I like the Phanteks Enthoo Pro, But i decided to get this case since its open, Like it isn't closed there are open spaces everywhere and it would allow more air to cool the components, And how about the Thermaltake Level 10 GT? Its a great case!
As for the GPU's, 2 290x 8 GB from Sapphire would do an awesome job, As for the CPU, I never knew the 9590 gets really hot.. I included it in the build as it will do an amazing job if i play CPU based games. But i'll take your suggestion and go with the 4790k!
