I know what you mean about the gears turning. Naja002 originally planted this idea in my head after posting his version.

But I didn't use his peace lilies because I have cats. At first I had some dwarf papyrus and corkscrew rush which are pond plants that can be submerged. I got them on clearance mainly because they were half dead. Took them out because I was having a hard time bringing them back to life and just left it with the other two.
Yeah you can literally put it anywhere and for any purpose as long as it has a light source either natural or artificial.
The glass was just pure luck. It just so happen to be the perfect width for my window sill. A ten gallon will be the cheapest unless you stumble on some really cheap glass. Building this small one was a piece of cake. Its the larger tanks that scare me. So unfortunately for you I have another "It was so easy". Just reread all of the tank building write ups and plan one out. The key is planing and it also helps if you have a partner
That ghetto overflow was plan B. Plan A was a nice plexiglas overflow box I built myself. The problem was it was to big. It sucked more water than the fluval could deliver. If I had a diamond drill bit the plumbing would have defiantly been different. Next time I will spend a little extra and drill instead of an overflow. It will look nicer and less parts.
The window box is a good idea. My girlfriend will defiantly go for that.
These pics were in its early stages when I had the pond plants.
I took this pic because I was excited that my pond snails were breeding.
