Out of interest Phil, how old is your PC?
For a number of years now my PC has been totally obsolete, MOBO has a CPU socket that is no longer in use, the CPU is not supported by Windows 11 and the RAM is no longer available.
For some reason my wallet keeps hiding itself!!!!
Which part

I bought a desktop PC around 1994-1995 I think, replacing an Amiga 1200.
It has gradually had components replaced over time, but I would guess around 2010 that none of the original components remained, so I suppose it could be considered a different machine from that point on.
It has a Gigabyte ATX/AM3 motherboard with an AMD Phenom II CPU, both bought in October 2011, along with two 1TB HDDs.
About 18 months ago, I moved the system partitions onto a 1TB SSD and doubled the memory to 32GB as DDR3 DIMMs had become quite cheap. It gained quite a performance boost from that, as it had become rather sluggish.
Although the CPU isn't on Microsoft's Win 11 list, the readiness checker doesn't complain about it, but the insurmountable problem is the lack of a TPM module, and the inability to install one that meets the requirements.
Not that I'm in any rush to "upgrade" to Win 11, I've only been using Win 10 as my primary OS for about a year!
Using my laptop (Lenovo T450/Win 10/Intel i5) in a docking station has made me realise that I can get along quite happily with a moderately powered PC. It also has an SSD though, which again seems to be the best performance upgrade for the money, compared to the speed of HDDs. Samsung 1TB SSDs can be had for less than £60 now.
Anyway, I managed to locate a suitable AM3/DDR3 motherboard today, with the required number of SATA and USB headers, so hopefully it will be up and running again before long.
My wallet generally behaves very similarly to yours
