This shouldn't matter at all to the system. Probably swapping the PCI slots would rearrange the drives to suit you, though I don't think you should even bother.
By the way, I just moved my system from sdc2 to sde1. Sda is nothing but a data drive, as is sdb, and sdc just got cycled out of service (used to be system drive).
