Spoiler, but the answer is basically that old hardware rules the day because it lasts longer and is more reliable of timespans of decades.
DDR5 32GB is currently going for ~$330 on Amazon
DDR4 32GB is currently going for ~$130 on Amazon
DDR3 32GB is currently going for ~50 on Amazon (4x8GB)
For anyone where cost is a concern, using older hardware seems like a particularly easy choice, especially if a person is comfortable with a Linux environment, since the massive droves of recently retired Windows 10 incompatible hardware works great with your Linux distro of choice.
