Hi there I just read your post. I can build you that system you want and make it even better and still affordable.
Only thing different would be the color of the case from blue to silver but still the same make and model.
My system will include a CDRW Burner instead of the regular CD ROM
A 256MB PCI-E XFX Geforce Card instead of the Old Sapphire 128MB AGP
The motherboard would be a an ASUS K8N4-E DELUXE nVIDIA nFORCE4 SLI CHIPSET Socket 754
With the AMD Sempron 3400+ Socket 754 CPU
+ Il preinstall Windows XP pro, Office XP Pro, Publisher XP, Mcafee Internet Secuirty Center, Nero Burning Rom, Antivirus, and many other other software for free.
