Ok, I'm just wondering if my idea will work ok. This is what I want to do. I have about 6 blue LED's, that I'd like to connect to my HDD Activity header on the motherboard. I want to place these LED's througout the case, so when it loads it flashes ect. Now, if I hook the LED's up in a series, will I have any problems with running them off the HDD header? I could hook them up in either a series, or parallel, but a series seems a little more efficent to me. Thanks.
