overall, ive almost always found better deals at newegg and their service is #1 Newegg.com - Computer Products, Laptops, Electronics, HDTVs, Digital Cameras and More!
the monitor: its probably ok, i like samsung myself; but if youre going to get a 22 inch screen, it needs to be at least 1920 x 1080
speakers: that seems like a lot of money for speakers... but if you know that they are excellent and youre an audiophile of some type, youll probably want a sound card too http://www.newegg.com/Product/Produc...82E16829132020
you may want to upgrade your case a little bit. i used to cheap out, and the cuts on my hands and the few years i got out of it showed. i would pay just a little bit more for the antec 900 or 300 or my own case Newegg.com - COOLER MASTER Storm Scout SGC-2000-KKN1-GP Black Steel / Plastic ATX Mid Tower Computer Case
power supply: im not sure on that particular model. ive found corsair to be a great brand in general, but i have never had problems with corsair power supplies. check out (pretty sure its not too far out of date) the power supply guide: *READ FIRST* Updated Power supply guide
video card: if you want to do some horizon gaming, the 5770 probably isnt going to cut it. i would look at an xfx branded 6850 or above or a gtx 470 or above Graphics Performance List
