The last time I went through an acquiring phase was a few years ago - all that early 2007-2013 stuff was so cheap....
I do feel that i now have enough and my pattern of usage has changed over the last 5 or so years anyway
I don't really use 32 bit systems any more - a 64 bit system with win 7 and moderate/budget card can handle everything up to near mid 2010's anyway (if not too insistent on maxed graphics in later games) via a mix of gog, patches, dosbox, emulation/virtualisation (hardly needed). The better of those machines are also good for linux and online
The experience of the game is made available in almost all cases without need for a machine from the game's era
I still have lots of machines and components, more than enough i suspect even if they prove less than averagely reliable. I still occasionally use an older machine for fun, old software and other specific uses, just lots less than i used to
I still enjoy the whole scene, but i really think i've stopped with buying vintage pc things now.
I wont deliberately purge things though, that's only necessary if running out of room - its surprising how little room well ordered and stacked PCs and components can take! Also, my collection is low value - middling and budget everything and nothing really rare, so there isnt really any monetary incentive to sell either
