Today I still have a working Pentium 1 with hard disks in full operating order.

As for the 486, I brought it down to my dads when I moved, and switched to using his much more modern system. It did eventually "die" in 2007-2008. My dad threw it out after the clock chip failed on the motherboard. I was pretty bummed because it sounds like a fairly straightforward fix / such a minor issue, but he's as sentimental as I and referred to it as "an old clunker".
