That reminds me of one of my childhood PCs.

It was a hand-me-down K6-II with (I think) 233 MHz clock rate. The thing had a tiny fan on top of the cooler that was roughly 4x4cm (if even that). The poor thing generally worked quite nicely, but had stuck bearings so it required a little nudge to spin every time the machine was turned on. I didn't have the side panel on because that was just too much of a hassle and usually would just reach in and start the thing blindly.

I forgot that one day and the machine had been running for about an hour (low load, so nothing too bad). I reached in and promptly gave myself quite a nasty burn blister because I touched the cooler instead of the fan.
