I believe many of them were tossed rather than repaired. Whether that's enough to make them 'rare', considering the large quantity produced would be the question, but functioning original iMacs may become hard to find at some point. I spent a couple hundred bucks to repair mine a few years ago when the repair cost was about the same as the resale value. Apple wouldn't sell just the flyback transformer, and I had to fight with the shop to just sell me the reconditioned monitor board without having to pay them to install it. The ten-year anniversary of the imac was just a couple of months ago ("On-topic"). (* Monitor board is mounted vertically inside a metal cage along the left side of the CRT, rather than horizontally below the CRT in subsequent versions.)
