Mashie Design MDVA Audio Spectrum Analyzer
 

"Installation couldn't have been easier. The instructions are straight forward and easy to follow. It took me about 5 minutes total to connect the MDVA. You need two empty 5.25” drive bays to mount the MDVA. Finding a spare molex in my wiring nightmare was probably the most difficult task. One thing to remember before trying to install the MDVA, you need two 5.25” bays with no obstructions. In my Lian-Li V-1100, there are little slot rests for the individual drives (CD/DVD) to sit on top."
