Baffled by this article tbh. It can serve a purpose in those "is it still loading that 300Mb PS file, or has it hung" situations. Besides.. if the one on the shuttle is irritating, then it's a fault of the case designers for putting an insanely bright LED in it. A subtle, not too bright and well placed LED for drive activity is a useful thing sometimes. The ones in my case are hardly noticable unless you actually look away from the monitor and at the case.
