for some time now I have a new approach in the pieces that I procure, even if I can not use them now, I take them now that the availability is good and the price low or right, because I have intuited that in the future they will be very difficult to find or very expensive. when I have time and I need them I will already have them at home

I also try to be "ahead of the curve" holding onto S478 boards when people were throwing out saying they will never be desirable. Kind of knew that wouldn't be the case with their AGP, IDE and Native Win98 support.
Same now with a lot been thrown out still having official XP support, and can imagine same again with the very end of Win 7 supported hardware.

At the moment you can get this stuff for free but does mean you need to hold onto hardware for about 15+ years for prices to start creeping back up. but if you have the space then it's not a bad way to make some money and save hardware while your at it.

I stick to anything interesting that is dirt cheap, even if I won't get around to messing with it for a while.

People are under the impression there are stacks of newer hardware in people's attics like the good old 286 to Pentium era when machines cost a ton and were saved because of that (before recycling was a big thing). Prices for most things (outside of recent GPUs) have dropped to the point that after you get a new machine you let the kids destroy the old one and then recycle it. You might as well snag it when its worthless and let it sit till you get the urge to play with it.
