The only place I found that carries it is
A-Power.com - Buy Enermax ECA3162-B (Black) Phoenix Neo SECC & Alluminum ATX Mid Tower Case w/25cm Fan & extra front 12CM LED Fan #11117 - CPEC3162B - Canada
and it is not the cheapest at $105.
If you look at that website it says it is a special order:
There is not enough information to determine the ETA or availability for this product, availability cannot be guaranteed. You may contact us for detailed information on this product.
So most likely just like the other 44 websites I've checked this case is discontinued.
