World-famous case modder Mashie has created this unique case modding accessory. It is a stereo 7-channel real-time spectrum analyzer which shows beautiful patterns on 112 LEDs. It goes into two 5.25" drive bays and does not require any additional software because it comes with its own microprocessor on-board.Mashie Design Visual Audio Review
