Case: Unless you are thinking of over-clocking then in my opinion this is a little large, I had something similar and added castors to it just to move the dam thing. I have downsized to the Corsair 300R and the Lian li PC8FIB and the Fractal Core 1000 all are a nice size for my ATX components but more importantly I can move them easily.
Monitor: This is an excellent choice, I have just given mine to my better half after upgrading to the 2711. The Dell's are fantastic monitors.I have an Acer as a secondary monitor and there is no comparison in quality, sharpness of image, colour reproduction,connections and adjustability.
Good choice and size of SSD. I have this size and still have around 50% free.
I am not convinced of the benefits of Ivy Bridge but that is a personal choice.
I assume that you are using Win 7 64BIT, even so, unless you really will need the 16GB or RAM,half that would probably be ample.
Good choice of cooler,I have the Antec Kühler 920 as it was on offer and comes with a three year warranty. They are both excellent coolers and very quiet.
PSU.fine, good and reliable brand.
