Building a new gaming rig... turned into anguish...

I'm building a new gaming rig. Here it is! 
Win 7 Ultimate 64-Bit
1 TB 7200 RPM sATA HDD
4 GB DDR2-800 SDRAM
Pentium D 930 Dual-Core Processor @ 3.0 GHz
Linkworld Electronics LC323 ATX Mid Tower Case
Gigabyte GA-G41M-ES2L LGA 775 G41 mATX Motherboard
Kingwin 750 Watt ATX Power Supply
AND (also given to me for free)
A Nvidia Ge-Force 9600 GT (96w)!
(I got a special limited edition card too, it was made by XFX on a Nvidia board... odd enough...)
All this for $352 USD!
God I'm so happy! *wipes tears from his eyes*
What do you all think about this build?
