So, looking at making my first pc build mainly for dcs and tried checking the difference in OEM and standard options, mostly what i read was warranty and packaging was the main ones but usually only a small difference in price, this however is a big difference of nearly 70 pounds!? Is it worth going OEM ?     
cheers guys.
