Reminds me of how when the Playstation 2 came out, Sony started planting articles about how it was so powerful that the Iraqi government was buying thousands of them to turn into a supercomputer (including unnamed military officials bringing up Sony marketing points). https://www.wnd.com/2000/12/7640/
A quick google will show you that it was. I remember because I was in college at the time and that's how I learned what a Beowulf cluster was. Maybe PS3 was more successful or more popular, but there were definitely PS2 clusters.
