^ that PSU is worthless for a build of this magnitude, IMO. Only 14A on one rail and 15A on the other. And why get a 4x1GB kit when you can get a 2x2GB kit for
$9 more? And why not get the 640GB HDD for $5 more? Great deal on the GPU... $133 after MIR for the 9600GT and The Witcher.
Just make sure you use care and caution when building. Get an anti-static wrist strap for under $10 and maybe even an anti-static work mat...
-install the PSU and plug it into the wall outlet to ground the chassis
-attach the anti-static strap to the case on some bare metal
-start installing components. never handle a component without wearing the static strap and never leave a component out of it's static protective packaging unless it's being installed.
...remember, it only takes about 25V to damage an IC. Your body can build up 15,000+ volts of potential just from walking across the carpet in socks. As this kind of discharge may not render a component outright unusable, more often than not it can cause problems during operation that may worsen over time.
And I'll bet 66% of DIY'ers don't take adequate precautions for something that can so easily be guarded against.
