Yes, I did that a couple of times. When some old HDDs of between 2GB and 4GB died on me, those HDDs had 512kb of cache, and they used those chips used on my PCI cards. So, because the HDDs died and served no more use, I stripped that memory chips from the PCB and stuffed it on my then new Trident 9680 cards or Cirrus cards. I'll post images later if I remember. Images of HDDs PCB I'm keeping just to trip the memory, and images of the card I still have, that use chips from them.
I guess is the same with EDO or FPM SIMM memory. You just have to use a soldering iron and make your way with those chips.

I have a pair of old PCI cards laying around that have chip sockets. I remember back when I regularly still dealt with old Pentium era equipment, I'd often times take cards I had trouble with or just had a crappy chipset and pry the memory chips off if they were the type that could fit in the socket. Come to think of it, I remember that the two chips in the sockets on the AT24 card I have were pried off a dead PackardBell's motherboard.

Since things advance too quick now, I guess it's not practical to have things as modular as back in the 90s but it seemed those big memory chips were around long enough that it might have been practical; after getting a nicer video card just scrap the memory off your old one.
