Thanks for the reply! I think I will forgoe the 200/230 mm top exhaust because I will be puliing more air into the case through the exhaust as you mentioned. Would 2 x 120mm front and 1 x 120 rear create more equalization? and have the top just left as mesh.
Removing the xdock PCB will only remove the frame work behind the clips while leaving the front clips for the xdock in place? I dont want a big gaping hole there either.
I didn't take mine off but from what I see taking off that PCB will then only expose the rear of the Hotswap bays and you won't have a gaping hole.
To the first paragraph: what are you using as a CPU cooler? Otherwise with the system I built in this case for my brother there's 2 140mm medium speed Yate Loon fans as intake and 1 120mm medium speed Yate Loon as an exhaust controlled using a Sunbeam Rheosmart 3 channel fan controller incorporated inside the case and using a Cooler Master Hyper 212 Evo CPU cooler. This is i5 2500k running at stock speed and all is well in cooling. There's photos of this build in this thread.
