for anybody who knows what they're doing.
computers can be put to innumerable different uses.
maybe you want to use one as a sever, or one to feed movies downloaded from the internet directly into your tv - bypassing the need for a dvd player or whatever. maybe you want a separate computer for programming and one for entertainment. maybe you want several to set up a test network for practising security related skills. maybe you want a computer next to your toilet so you can surf the net while you're taking a crap (i haven't done this myself, but it's an interesting idea).
all you need is a little imagination and a little technical knowledge.
what are old consoles good for? being "collectors items", collecting dust?
