Quite a bit to see inside. A lot of it is what I expected. Quite the beefy 12V power supply then a second power supply for PoE power. A lot of the back ports were ran off PCI express style cards. I'm not sure why the cooling is designed the way it was. Very nice touch making the fans easily replaceable though. The amplifier board was impressive. The 70V/100V speaker transformer was not expected.
