I'm not sure what brand it is. I bought if off ebay, the seller makes them apparently, but it's very professional looking. The corners are rounded where the plexiglass is bent rather than glued.
I use the overflow box, since my tank was already set up and it would have been a major pain to drill it.
Check ebay before you buy one though, the LFS here sell them for abotu $300 I believe, that's all inclusive, pump, overflow box, and media. I gave $150 for mine.
I moved the HOB filter to another tank that does not have java moss in it lol.
I decided to check ebay before finishing the post. looks like there's only one there. It's similar, but not exactly the same as mine.

Mine has the media section taller than the side with the pump. That's a great deal there though with everything that comes with it, $150 shipped.
Ends in 3 hours though.
