I haven't had any PC component remain very upgradable at all
for the past many years

That's odd -- my PC has been fully upgradeable since I bought it in 1992.

Of course, it has had four new motherboards, two new video cards, three new cases, half a dozen new hard drives, four new RAM sets, two new sound cards, five new CPUs, two CD-ROM drives, two new monitors, two tape drives... but it is still the same, original computer because I am still using the original floppy drive and keyboard.

It's like great-grandfather's ax -- still going strong, even though it's had two new ax-heads and five new handles...
