I love the dual overflows and standard size socks! That is something that none of the other AIOs I've been looking at have. I'd be thrilled to win this because I have been shopping for an AIO in this size range. It would make a great tank for the very creatures that piqued my interest in this hobby 15 years ago: royal gramma, sixline wrasse, and coral banded shrimp.
Bonus entry #1 : I like the TRUE TEMP digital heater controller you have as it seems to pretty much be compatible with any heater on the market. Also impressed that it boasts to be within .5 degree accuracy.
Official Entry: I really like the idea of having the filter socks also hold the filter media. Seems like it would save space. I'd be curious to see the results of this method, and wonder about flow backing up or how often things would need to be cleaned and replaced.
