I do it all the time...well, until Abit sent me some cool black ones with this new mobo.
Two rules:
*Reuse the black plug on the end, not the grey middle one. There's one pin missing in the middle one.
*If you have a raid, make them as close as you can to the exact same length.
It also helps to mark it before you remove it, so you don't change it around.
