Thanks for all the great feedback!
Re: warping - this is an unfortunate side effect of the uneven heating when hand soldering the mounting bosses. some came out more bowed than others after soldering -
Reheating the board evenly a couple of times should flatten it out again. I suggest mounting it temporarily without springs, leave the screws slightly loose, and put the glass plate on top - and a heavy weight on top of that to help especially as it cools off. if your running it at 12V its safe to run it full-on unregulated , the temp in open air will top out at around 120C, and with some insulation around it, a little higher. The board can stand up to 160 -170C, and the closer you get to that temp, the quicker it should flatten out.
Re unused Quantum mounting holes: You're the first to mention this, so i didnt think it would be an issue for anyone - Had i known this would be an issue for you i would have offered filled them with high-temp epoxy to give you an unbroken surface.
You could try that yourself: i would laminate the top with kapton film first and clamp a flat surface (glass plate) to the top, flip it upside-down, then pour in a few drops of J-B WELD in each hole.
