Here's one for you.

Does anyone remember the so called liquid cooled dreamcasts. The story was the so called chips ran so hot in the initial production they had to be liquid cooled. Well I remember when I bought my system on dreamcast launch day and mine wasn't that version. I hunted around until I found one at another store I was told you could tell by looking in the fan vent the non liquid cooled was plastic and I think the so called liquid cooled was metal. I finally snaged the metal but never opened up a dreamcast to confirm.

Seeing this thread brought back that crazy memory of one mans quest to get hot technology. Funny thing is the non liquid cooled was the second or so revision that was possibly a better dreamcast.

Truth or rumor I have to investigate.
