My old tech is mostly desktop PC stuff (complete rigs or components). I like to turn them into retro-gaming machines, just for fun and to nurture my nostalgia. I have several of them already, ranging from mid-90's running under Win 95 / 98SE to late-00's under XP.
Among them, I even have a few ones that a friend of mine gave me after salvaging them from the landfill. Yep! And sometimes they were dumped for reasons as petty as a flat BIOS battery. SMH. So I revived most of them and use them for various experiments.
Throwback to that one Athlon 64 platform in perfect condition that was my guinea pig for my first serious overclocking attempts. Don't worry, I didn't fry it in the process, but it has been put in storage now.
I also recycled some of my old components to put together / upgrade my parents home PC. And my previous rig currently serves me to get familiar with Linux, as I'm actively preparing to transition. Regarding what Windows is becoming, the deadline will probably be Win10's end of support...
So basically, I'm struggling a bit to not become a hoarder.
