I haven't totally figured that out yet. The main color is going to be red, because of my color scheme, but I am thinking about getting a few sets of lighted case feet in different colors red, blue, green and UV. The sets use 4-5mm LEDs and can flash in different patterns. plus the power LED and HD LED are in there too. This way I can light it to suit my mood, or just show off. plus the fans are red too. Also I am going to make my own power button and light it too. Now that I think about it, I have a question... Can I run 2 LEDs off of the power LED jumper on my mobo, or is that not a good idea?
