Query: Great power suppply

I've had one of these on my homebuilt desktop for 3 years and it works fantastic. This one was for my brother and I went with it because of the reliability of mine. Plus, if you have a custom case with a clear side, it lights up the inside quite nicely. The fan controller on the back is great for helping to regulate the temperature while keeping the noise level down.
