That's where I got the "MB" from. It stands for Mini-Bow. You can find them at Petsmart, Petco, or pretty much any decent aquarium supply store. The cheapest I've ever seen them is at Wal-Mart, you can't beat 35 bucks. They come in a few different sizes, 2.5 gallons, 5gal(which is the one I have), and a 7 gal. The 2.5 and the 5 are acrylic, all of the 7's I've seen are glass. They come in a bunch of different colors too. I think they're cool cause you you can pretty much mod them anyway you want to suit your needs. They come with a crappy Whisper internal filter, I just ripped the pump off and glued on a suction cup and bada-boom, instant powerhead. Then I added a decent HOB filter and upgraded the lighting to a 20 watt pc bulb. That's all I did but I've seen everything from adding moonlights to the hood to adding a spraybar for a wavemaker. And even then when all is said and done you'll probably still end up spending less than if you purchased one of those "complete systems" like the Nano-cube or Aquapod.
