Hmm, Neptune sized planet in habitable zone? Sounds like a fairly good canditate for an optical SETI search.
Despite it having a mass of 24 times the Earth, this planet might have Earth sized or smaller moons, which could have liquid water and therefore the potential for life.
Due to the presence of gas giants in the system, it is likely that most harmful comets and asteroids would be removed therefore increasing the chances for a stable environment able to support complex life.
Wonder if the SETI guys have considered looking for entangled photons, as this would be a very effective way to determine that any signal was from an intelligence and not from a natural phenomena such as a microwave laser formed between the inner planet and the star's magnetic fields interacting.
A recent study also suggests that due to the K-T and Permian impacts and other more ancient ones, life containing rocks from Earth might have made it as far as HD10180 if not further, so if we do find life there it might be essentially the same bases and nucleotides as here on Earth.
Even more interesting is the possibility that complex life such as spores might have survived the trip allowing evolution to "jump start" far more quickly than from scratch. So if we do find something interesting then it could be as complex as say the early ocean dwelling fish.

IIRC detecting entangled photons is possible using two sensors at geographically separate locations pointing in the same direction. If both detect a photon at the same moment then it is very likely that the photons were entangled.
A similar method is used to detect the particle showers from cosmic rays IIRC.
Another interesting method is to use polarisation sensitive detectors as a significant imbalance suggests a laser light source rather than run-of-the-mill star light.

HD10180 has a possibly habitable planet?
If my understanding of QM is even remotely right, they don't look any different to normal ones.
