A nice looking box!
Conclusions: I haven't been able to find any serious issues in the stock firmware, the box is absolutely fine. The cooling solution is pretty standard (and definitely better than H96's). For example, leaving the Riptide Renegade demo running for a while, gets the temps to about 80-82C (with an ambient temp. of about 20C). There are no stability problems due to overheating!
All in all, I'm very satisfied.
