I had one of these :-)
Edit: I liked the video! I love old hardware :-)
I agree on the music with the other comment - either make it stand out/vary it or remove it, it gets monotonous after a while. Narration would be nice, but it's not required.
I found myself fast forwarding quite a bit - i appreciated the level of detail you went with cleaning the card for example, but one gets the gist after seeing how the die and the first part of the pcb got cleaned, no need to show the whole process in full length/normal speed + the cooler, and show the reassembly after already seeing the disassembly when there isn't anything to watch out for when doing it in reverse.
