Also, I'm placing this information here for posterity.
After reaching out to Novelkeys and Soran, I have the following information:
MKB screwed up and included the wrong screws for the case (this also effects all NovelKeys orders). You may or may not have noticed that when you assemble with the included screws, the top edge will pull apart by a few millimeters. All of the case screws should be M3x4 (ISO 4762). They screwed up and included 1/2 of them the wrong length (too long).
Any M3x5 or M3x6 should work. I would suggest people with powder coated cases to make sure they use screws where the head is fairly compact (not knurled). Those holes get pretty tight on coated cases.
