These are the stories I love. A person finds a need and fills it. This seller makes CNC machined tanks for the Aspire Nautilus. When I first pimped his original design about a month ago - it sold like crazy. Over a 1,000 went in just a few days. He has since added to his line up with new designs. These really give a new look to your Aspire. I have a few and they are really fine quality. Prices will vary according to the intricacy and time it takes to make the tank.
