The Node 304 arrived today and I learned that the holes in the drive mounting trays are not spaced correctly for 2.5" drives. It's only a hair off, but enough that you can only screw in two screws on the same side of the drive. I got the calipers out to see what the problem was and the issue is that the 2.5" HDD holes are 2.434" on center and the Node 304 tray's holes are 2.412" on center. That .022" difference is enough to make it impossible to thread the screws on one side without stripping...
