Use google (or whatever you prefer) and search on "trimless aquariums". I did and found this link:
Blue Series Aquariums and Packages
I'm sure there were more. Check it out.
IMO, in theory the tanks look very cool. I have seen them in person and they really stand out. My problem with them is that the ones I've seen don't make it easy to hide your plumbing. Many don't even have overflows. What's the point in having a beautiful tank if the plumbing is going to be obvious?
IMO.
