No you do not. If any yard try to tell you they are down grading your PCI cards because of the metal tell them to go to hell.

On all high grade motherboards (desktop), server or PCI cards there is amount of steel that is "ok" but if there is to much then it will be down graded.



I.E don't leave the HUGE metal back plate thats on the dell desktop motherboards as your boards will be down graded.
