Blue LED, GD access light on the front/face, Fan LED, and an internal SD mod above the modem. Though no card was inserted when I took this picture
Nothing fancy. Just an old CRT monitor next to my PC monitor which I prefer
Edit: Oh and monitor headphones (monitor speakers meaning for sound mixing) directly into an RCA->3.5mm female jack. No volume control or anything just sound directly from the console to the monitor headphones
