That is likely true, but it was the same Sony Trinitron used in the Color Classic. Thanks for reminding me about the 580, that truly was the ugly duckling of an already deformed product line. In fact the same cheap monitor in the 5000 series destroyed any aesthetic beauty of that machine which was designed to use the Trinitron "flat" screen. Damn you Apple!
In deference to gobabushka, there was nothing wrong with the innards of the 500 series (which is why I want to transplant them into a Colour Classic). But that design ... oy, what a mess. It's like a CC on steroids and, like some kind of obsessed bodybuilder, its legs are too small for the swelled upper body and it has this huge unwieldy chunky case that just doesn't fit anywhere. The Mac TV interestingly enough was the only one I would tolerate as that black case had a way of mitigating the rushed design flaws.
