I'm not big on monitors so I'm can't really tell the difference between something good or bad, the list MSschmiess isn't terrible I just have a few suggestions.
Mobo/Proccessor i'll leave alone, they seem okay for now
Graphics I'd definitely buy a 7600gt+, preferably a 7900gt or 8800GTS
PSU, I'd get http://www.newegg.com/Product/Produc...82E16817341002
Case is up to you and apparently you already have a hard drive, though I'm not very fond of Maxtor.
Peripherals, if you need speakers/keyboard/mouse, take a look at Logitech.
