I'm all in on this (either white or black for me). Loved the sound signature of v1, and joined the hobby right after it released. But I'd like to mention my thoughts on the following:
1. Definitely a default 2U Backspace for HS. I'd imagine there's a large overlap of beginner customers who don't have a soldering iron, and are used to 2U.
2. I would prefer no engraving, but I understand the desire to have one (for resale and keeping people from passing this off as a V1). I would maybe recommend an internal engraving on the top/bottom case instead. Or just cleaning up the "Polaris V2" to just "V2" or something else.
3. I don't mean to be one of those guys (even though I am), but it would be awesome to see the option of anti-static PE foam, so builders can experiment. Of course, if that's not the desired sound signature of the designer, it makes sense to not include it.
4. Lastly, since the weight is SS, I think it'd be awesome to see a clear coated/mirror coated version as well. Of course, price should be the main consideration when creating this stuff.
