I got a bunch of LED fans all connected to a home-made "junction" box with a speed reduction cable to the jumper on the mobo. Neat, and quiet. I use "lazer" LED`s instead of cold cathode coz I like the glow effect instead of bright lioghts, but thats just a preference. On my old comp, I changed the power and HD LED`s, still to do that to my new one. I added switches to the front (of the old one) for the cold cathodes I had. Made my own window side panel (
www.diyplas.co.uk) they sell plastics for glazers etc, but I got plastic sheeting there very cheap- made a side panel with it and some dremel "skills". So much cheaper than a window kit
Modding is great, esp if it goes the way the builder hopes for
