They start to built up but i clean out occasionally and don't keep more than 5 of any type. I have never run out and also every device comes with a cable.

5 is arbitrary but it keeps the problem under control.

Don't let junk take off your life. Every square foot of space has a cost. If the thing being stored is not more valuable (emotionally, dollar value, whatever) than the space it sits in, get rid of it.
