(could be) funny story

The other day i took a two win98 computers, one was a Dell and one was a Compaq. I got bored so i gutted the to machines and swapped the parts out just to see what would happen. Well at first it said that it was not compatible so i went and messed with the setting and it turned on and was working. Lol it is funny to me because they (i.e. the computer making companies) don't try to hard to keep their parts THEIR parts. i don't know how well this would work on an updated machine. Probably not very well though.
