So I've been looking to build my first gaming rig, and my dad found this computer at his work, brand new: http://www.pcworld.com/product/29019/dell-xps-410.html

These are the new parts I would buy:
Graphics Card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202006
RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314
Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157302
Processor: http://www.newegg.com/Product/Product.aspx?Item=N82E16819116782
PSU: PC Power & Cooling Silencer 750 EPS12V 750W EPS12V Power Supply

So I would just be keeping the optical drive, case, and hard drive from the original computer. Are there any suggestions for change? Also will the graphics card fit in that case?

Thanks
