This video shows how I converted some free computer power supplies that were salvaged from St Sebastian Catholic School in Belle Vernon, PA In 2013, I converted my light display over to RGB low voltage LED lighting. There is a lot more do-it-yourself work involved but I've been able to keep the costs lower and produce more effects for the display. The recovery and salvage of these power supplies will save me lots of money for all my future application. I highly suggest you ask your friends and family if they know of anyone getting rid of their old computers. It turned out to be FREE endless supply of an important component in the RGB lighting hobby.
