No Wires..... Ever Wifey Dearest Audio Riddle

Much to my horror -- despite the persistance of my "exotic cable fetish" -- I seem to be buckling under the pressure of family life and thinking about -- gasp -- hiding all of my exotic wires.

Some of you may have read one of my earlier posts on a WAF friendly pedestal concept to hide multiple components in a pleasantly modern column.

It has occured to me however, that if entirely enclosed this might present some ventilation problems, or expose a tangle or wires behind the rack when opened up from behind to allow ventilation.

Therefore, does anyone know where I could buy perforated metal, like the type that is used to cover tube preamps? Maybe two sheets of that could sandwich a spaghetti tangle of wires yet still allow some air to flow.

Any other hide the wire ideas?
