Meh. I'm running an Athlon II X2 250, 65W TDP, i.e. same CPU family
(0x10/16), running at 3.0 GHz with 4GiB DDR3 RAM ... After (again)
over 10 years, I'd like to upgrade again a bit, Ryzen 5000 4-8core
w/32GiB RAM like ;)

Beware: I use a lot of disks and I tried running it with then 8 (or 9? 
or 10? Lots!) HDDs with a 500W (or even 550W) PSU. System wouldn't
reliably boot up. Replaced with a 650W PSU and it's running since
(which is, those 10+ years now :) Currently I have a SSD and 7 HDDs
(and 2 DVD[1]) ;)

Typical spinning rust drives are (or at least were) specced to take up
to about 30W while spinning up, ~10-12W-ish on access, ~5-7W-ish while
idle. For me, that then was ~240-300W alone for all the drives at
power-on. Too much obviously for the 500W PSU along with all the rest
of the box also starting ;)

I've got a nice Seasonic PSU from Corsair (TX650 v2) (the v1 was some
other stuff), only drawback is that it has gotten a bit clogged up
with dust and gotten loud and there's no easy way to clean it out (at
least without taking it apart) *sigh*...

Nope. NFS is "Network File System". You mean "NAS" = "Network Attached
Storage" ;)

Also, that Phenom X6 w/ 125W TDP is plenty powerhungry, even at idle
(ISTR 50W-ish, while modern stuff can take only 20-10W for the system,
aside from the HDDs in both cases).

No idea, but I'd go for a different case. And probably, depending on
budget vs. power-consumption (cost) for a different CPU+MoBo+RAM,
something like a AMD Ryzen 3 3200G or maybe a x86 Celeron/Pentium/i3...

HTH,
