Yes a dedicated GPU fan is what I am referring to, of which the HAF X has a large one stock and has the ability to have a second one installed. The GPU fan does help, I've never once seen temps as good as I have now with my HAF X. I barely break 60c and that's only occasionally in certain games. Yes I know up to 80c is safe but I'll take 60c over 80c any day of the week as it helps keep other case temps and my room temp down.
And on the note about the SSD Cyanotical is correct, one of the best overall SSD is the Intel 320 and it's only SATA II. Because of it's performance it ends up being faster then some SATA III models. The data transfer rate is not where you will notice the biggest difference in performance.
