I built it myself a long while back, before led lights were commercial available and just being talked about. I found some very very obscure website back then selling pcbs, and i found a pcb that was a 72 led array + resistors. I bought 14,000mcd leds on ebay, and soldered it all up. I then build a little acrylic box, painted the inside white, painted the outside black, and made a whole for a 30mm fan
I'll get you pics tomorrow
