I’m sure there’s some random stuff, coins that were minted in the 50’s, 60’s, 70’s etc, some clothes that I got in the 90’s that are pushed in the back of a closet, items that I had when I lived at home that followed me to college (an acoustic guitar I never really learned to play from around 1996ish) and random stuff like that but, realistically, probably my desktop computer.
I’d count that mainly because it’s the first thing I think of and I actually use it on a regular basis. My parents got it for me when I went to college in 1998, so, 16 years ago. Over the years it’s been upgraded numerous times. It’s up to 4 hard drives, I’ve added memory, replaced the motherboard, DVD-writer, upgraded the sound and video card, it’s on it’s third monitor and I don’t even know how many keyboards and mice it’s seen, the power supply has been replaced at least once, maybe twice (possibly three times), all the internal cables and fans have been upgraded, hell, it’s not even in the same case. But, it’s still the same computer, to me anyways. It does, however, have the original C:\ drive, CD ROM and 3.5 inch floppy drive.
Also, several years before I’d ever seen a see through case on shelf, I happened to see a kit for putting a window in the side of the case on ebay so I did that myself. Then, a few months later I bought some blue LED lights for another project that I abandoned and thought they’d look pretty cool mounted around the edge of the window (on the inside). Again, I’d never seen or heard of a computer with a window and lights in it. It was pretty neat looking (still would be I suppose if I plugged the lights in). I also had car cigarette lighter mounted in one of the front panels at one point as well.
Like I said, I’m sure I have older stuff around here, but that’s the thing I think of. The house was built in 1997, I moved in in 2005 and I’m not a hoarder.
