To be honest, the case is still the original one, but almost every other part has since been replaced. Now, I’ve taken it back to the shop where I bought it 20 years ago and asked them to upgrade the motherboard, CPU, and memory - the last of the original parts.
So, is it still the same computer?
I also like that I can just keep replacing parts on an existing product rather than buying an entirely new device each time. That’s exceedingly rare feature these days.
I had my computer in an old AT case until like 2018 or so. I finally splurged and got myself a $60 Montech case with the power supply on the bottom. It’s always been like that - swap out motherboard, cpu, ram, and toss everything else back in.
