This isn't a silver bullet and it can still get expensive, but i only replace what needs replacing, and spread out the upgrades over time so it's not a huge rebuild. Also when you do upgrade don't go for the top of the line new years models, get what's effective at power per $ from previous lineups.
These days, GPUs probably need to be upgraded every 3-4 years (but you don't need to buy the latest and greatest).
PSU almost never needs to be upgraded.
CPU Mobo RAM kinda need to be replaced all at once but you can do that like every 8 years and still run new stuff. Again, you don't need to buy the current years models on those. RAM you can space out if you want to, as well.

Storage is also on its own cycle.
