I was lucky enough to get my hands on the prototypes of the board (e-white and dark blue). Overall, it boasts a great balance between design and heft, with quality finish you can expect from EVE. I didn't notice any other engravings other than ones representing the board (the VNMK engraving/badge up top and serial number down at the bottom).
To clear the air a bit, I think the main reason for Truong (VNMK Admin) to keep the number of boards available low is to play it safe and make it right. This is his first time running a custom board GB, and he has been very cautious and thorough every step of the way, and he only decided to post an IC on GH after having received and inspected the prototypes. The part where he will not be making any profit is true, and though the wording may throw some of you off, I truly believe there's all good intent behind this project.
I do, though, think that raffle sale is a better fit for such low number of available units. If GH users' demand for this board is greater than what's currently available, it will be shown in the IC data, and hopefully play a part in the runner's final decision.
