Keeping all 120 or 140 size would help with fan control so you could run them all off the same controller, but if you don't mind splitting the 120 and 140 fans on different controllers then you can mix and match 120 and 140 sizes. Bottom line is cram as much rad space in there as you can and the budget will allow, it's a lot less headache in the long run than trying to tweak minimal rad space to get good performance.
You might also want to visit the owner's club to ask more specific questions about the case and see what other people have done.
To clarify, I think an extra 120mm of radiator for Oc'ing for each component Oc'ed. This 120 figure is also relative to how much overclocking is being done and how good the silicone lottery treated you. A stock CPU cooling nicely with a 240mm radiator may may need 2x 240mm radiators with a heavy OC. It's all about TDP wattage / heat.
Fan speed control is rather easy, especially if PWM fans are used. A single PWM signal will easily control 8-10 PWM fans. Well, most PWM fans. Some corsail PWMs don't play nice and only 2 or 3 will work. But most people don't consider them good fans. Fan speed control is easier if all fans are the same, but a little planning and it is not hard to pick 120mm and 140mm fans with rpm ranges that will flow similar amounts of air using same PWM signal rate.
I'm still waiting for ciarlatano's suggestions.Edited by doyll - 6/28/16 at 11:10pm
