Does it matter which way I plut in my Harddrive activity light and other "Case" cables into the motherboard?

I am reinstalling my "PC Case" cables into my motherboard and I was wondering if it matters which way I install them (i.e. facing up or facing down). These are the cables that control the Hardrive LED Indicator and the Power Button on the case.

Thanks, I really appreciate the help.

Power and reset switches have no polarity, so connect them any way you want.

LED leads need to have the proper polarity. There will usually be a small + or delta stamped on the positive side. The colored side is usually positive. If you get it backeard, no problem. The led just won.t work and you can reverse the connection.
