I usually have 8 or 16GB is my computers because I can. Most of the computers I use are around 6 - 11 years old, but can still be upgraded to 16 or 32GB memory.

I am getting into more retro hardware, but even then the Core 2 Duo and similar platforms can be often be upgraded to 8GB memory. I have access to a lot of hardware because my business is repairing and refurbishing computers.

One of my projects right now is a Dell Precision T5400 that I plan to upgrade with two LGA771 Xeon processors and 32GB of PC2 ECC memory.

I am interested in what you wrote here:

Can you elaborate on that or do you have links to any documentation about running a 32-bit subsystem for some programs?
