I've got a similar style of tank, just cube shaped.
It definitely has it's downsides, primarily in the reduced display area and in my tank, the filtration was designed for salt water so it's not 100% ideal for freshwater. I find there is not enough fine media and not many options for adding it.
Conversely, I LOVE the all-in-one aspect. Everything is in my tank and hidden, no ugly filter intakes or heaters cluttering up my display space.
