very cool. my advice is to seriously think about doing something to prevent moisture damage. a little juice is all it takes, seen it a few time now already.
the options I can think of is either coat it with clear silicone, or coat it with hot glue or coat it with liquid electrical tape. the dna display works awesome until the board gets a little damp from juice. another thing I'm considering for future dna20's is neverwet, it's a 2 part spray, like a clearcoat type thing, and it supposedly waterproofs well enough that you can submerge it fully while under power. guys have sprayed computer motherboards then installed them in fishtanks fully operating under water with this spray I think. it's ~$20 at home depot. technically the manufacturer doesn't recommend it for electronics but lots have used it anyway with amazing results from the little I've read about it.
mines already epoxied in place so I may have to use one of the other options, silicone or hotglue both sound like good options too, then there's the option of googling for a true conformal coating too which is probably the real pro way of doing it I guess, but some of the amateur solutions can work just as well. just some things to think about

great job getting it going in there, really cool mod.
