Old Computer Parts... Answered

Alright I know this question has been asked a hundred times before, but I've searched and none of them have been close to what I specifically want.

I have two old computers with some fans and L.E.D's, and I was just wanting to find something to use these things for. Everything I find is either about restoring the computer or just using the shell of one. I want something like robots lights or something like that.

Oh, and sorry if this is in the wrong forum.
