computer case blue led lights?

[kenny1999]

hi

i often see people on forums post the photo of their cases and those cases looks beautiful with lots of "blue light" around

I want to know how to make those "blue light"? what's those lights called? Are they built-in features of some particular cases or are they aesthetic hardware ?

Example

The fans have LED's built into them. You can buy them at any computer store.

You can also buy LED light strips that plug into molex connectors and they also sell cold cathode tubes (also powered by a molex connector).

$10 to $20 in fans (just make sure you get the right size) will fill your case with light. The effect of the case in the picture is a bit more than that but I have 2 led fans (front 120mm and rear 80mm) and the case glows pretty well.
