I experienced problems with HDD overtemperatures in the summer of my external USB2 case. The case was using a noisy 40mm fan which was annoying. I thought in a bigger case with a bigger, slower running fan I will be better off. So I decided to build my own NAS

I experienced problems with hard drive over temperatures in the summer of 2007 with my external USB2 case. The case was using a noisy 40mm fan. I thought a larger PC case with bigger, slower running fans would help lowering the temperature without creating too much noise. So I decided to build my own NAS

  • Hook up your NSLU2. Use double sided tape to glue it flat on top of the 5.25'' drive bay. That way you have full control over the power switch and still see all four LEDs?
