Gorgeous board! Might be my first high-end 40/45% (acrylic or wine for me) if I convince myself I can use a 45 daily.
Super nice update, congrats! Bottom mounted & widened weight will look much better on acrylic (& on aluminum as well)!
USB looks much better there.
Can't say much on alignment & magnets without seeing the product, but you have my full trust!
Question : how is the weight (copper) attached to / keep together with the magnets? Glued? Same question between the magnets & the board (aluminum / acrylic).
