That looks great on a Hana! I usually hate boxmods, but maybe... I was actually looking into a vaporshark with the dna30 because of it's size, but that Hanna looks similar in size and likely has a better quality case.
Oh yeah, I also forgot to mention before that the Magma's top cap threading matches Kayfun tubes/tanks. I was goofing around and put a nano ring + clear tank section on the Magma and it looked neat, the magma cap doesn't have enough threads to go all the way down on the rings though, so there is a tiny gap. The Kayfun top cap on a Magma base looks pretty nice as well.
Considering the aftermarket support of the kayfun for top caps and tubes I bet you could put together some nice looking setups. I was hoping to figure out a way to use the Magma cap on a Kayfun, but there really isn't any way to seal the chimney top that I can see, and still have a drip tip used. Maybe a really, really large ID tip would work with some silicone from a carto-condom acting as a seal.
