Perhaps it would be a good idea stop stockpiling parts in general.
Point taken. I was tempted to post a picture of my "warehouse" (my living room and my bedroom closet walls), where I have new custom PCs stacked up, looking for buyers. If I don't find buyers, even at a small loss, by Christmas, I'll probably have to donate the rest of them. I have bi-annual housing inspections, and my hobby / side-gig is taking up too much of my living space. Yes, I have a storage unit. Yes, it's of decent size. Yes, it's full to capacity now. :|
Edit: I remember, five years ago, I donated all of my single-core machines, to get them out of my hair, since they were basically unsellable. Actually, could have been 7 years ago. Basically, back in the days of the Core2Duo and Athlon II.
Now, we're in the days of the G4560 2C/4T ("Pentium Gold") for $86, Ryzen 3 1200 4C/4T for $100 on ebay, and now, the i3-8100 CFL for $120, though that may even drop a little. It makes little sense to go with anything less, nowadays. The slight savings, when buying new, just isn't worth the performance hit.
And for those people with decent mid-range budgets, the i5-8400 and Ryzen 5 1600 would make good picks.
That's not to say that the G1820 Haswell Celerons are now useless, because they're not, they can still web browse pretty well, especially in Linux. Heck, even the FM1 A4-3420 APUs, are somewhat "bearable", if your expectations aren't too high. (Say, coming from a P4 or something pre-APU / pre-iGPU.) And the G3258 Haswell Pentium Anniv. Edition CPUs are darn speedy, for basic web browsing, when clocked to 4.0Ghz or above, although they may stutter playing GTA V.
Sad to say, I've even got some A4-6300 FM2 APUs, albeit with 2x4GB DDR3 and SSDs. Those Piledriver-derived APUs always struck me as somewhat laggy, for some reason. (Never been a fan of BD-derived architectures.)
