| I haven't had any luck in finding motherboards that would take the old CPU,
| RAM, and so on, but your story is inspirational.  The case is a CoolerMaster
| with lots of space in it, and it would be nice to be able to keep it.

What is your old motherboard?  CPU?  RAM?

The oldest i7 with 6 cores seems to be of the Haswell-E generation
(eg. Core i7-5820k).

The 6-core I7's seem to use sockets with more pins than the common
garden variety I7s.  This makes for more expensive motherboards and
they probably support more memory.

Even the oldest 6-core i7s seem to use DDR4.  Newer CPUs still use
DDR4.  So you might be able to reuse your RAM.  It might be slower
than what you'd want on a new build.

The first 6-core 12-thread i7 seems to be Skylake-x.  Like a Core
i7-7800x.  Suitable LGA 2066 motherboards are available and expensive.

I'd love to play with what you discard!  It would be newer and more
powerful than any of my desktops.

If you want a similarly high-end box but for modern times, you can go
crazy with a current ThreadRipper or Epyc AMD processor.  But you can
get quite a lot of power for less, as Lennart has outlined.
