I've done some tweaking to my build with GPU and it says "for the physical dimensions of The NZXT Source 530 ATX Full Tower Case supports video cards up to 444mm long, but video cards over 282mm may block drive bays. Since the Asus Radeon R9 280 3GB DirectCU II Video Card is 284mm long, some drive bays may not be usable."
Should I be worried b/c of the extra 2mm?
