![[VIC] Cable Tidy Box Set of 3 Stahl $2.00 / w phone holder Arlec $3.75 @ Bunnings, Waurn Ponds](http://files.ozbargain.com.au/n/30/834230.jpg?h=a0eb0748)
Found these today when looking for a cable management box for my cables. Waurn Ponds Bunnings. Doesn't seem to be on the website. I remember paying $30 or so for similar looking ones on Amazon. Great for keeping dust off the powerboards. The Arlec one has more ventilation on the sides if you're worried about heat.
Not sure if also in other stores, good luck.
