LED Assistance

Ok, this is what I'm trying to do. As mentioned in the one post below, I'm making legs for my one tower to keep it off the ground. I'd like to take 5mm blue LEDs and wire them into each of the 6 legs. The problem I'm having is that I have absolutely no electronics knowledge/experience and I'm not sure how I should go about this. There will be 6 blue LEDs that require 5V each. I'd like to have these on their own power supply independent of the computer whether it'd be batteries or some hack job on a wall outlet setup. I'm saying this because this base may end up being used for things that aren't computer towers later in it's life. Does anyone have any ideas?
