Game collectors question

Separate shelves for every console

A wiretidy. It's like a zipped sleeve that you can do to make sure the wires don't get tangled. I use one in my room to keep my screen/dvd player/freeview box/N64 all nice and tidy.

I use binder clips since they can easily be removed and work quite well!

You'll probably have to take the metal clip off to put the wires through since console controller plugs are rather big.
