Oldie/codgers R us! I match all of the above, except new(er) fridge, and house is much newer.
My 'office' PC is my next upgrade challenge. It's in a beautiful but freakin huge coolermaster case in custom colors from way before I retired, so sorely tempted to gut and put in new MB, etc, but all the new crop of mini-PCs are also hugely tempting. (I love the NUC skull canyon I got for audio), but am really spoiled by all the interconnectivity options of the huge case.
It
has required new power supply, upgraded (actually downgraded) video card (similar to OP's situation), and new HDs (recent drop in 2TB SS drive prices gave the thing a few more years I think). And reasonably frequent vacuuming and de-dusting, esp the CPU cooler radiator fins. Oh and magnetic snap on air filters help too.
Fun to think about, not likely to do much any time soon tho.
Why pay for new when the older stuff just keeps sold(i)ering on?
EVs keep dropping in price, so, maybe someday? Printed OLED screens will be with us in a year or so, and expect significant cost drops there, too.
