The tanks I got from an LFS, but many manufacturers make 30cm rimless cubes as they're very standard. If you're in the US you should be able to get them anywhere online, or at an LFS.

I used it in a 9gal cube and it worked pretty well, it is adjustable and not loud, my only complaint is it feels like it gets pretty warm, which might not be a big deal for you, but I didn't need any extra warmth when my tank was hitting temps above 80.
