Just to write back that I have also received the package today. I'm not sure what I expected for the replacement of the chipped glass panels, but I had a little chuckle when I unpackaged to find literally two panels of glass. So I had to go through the nerve-wracking process of carefully removing the previous glass from the aluminium frames, and VERY carefully stretch them over the new glass. The thought of "oh man, if I chip the glass this time, how long is it going to be before I can get another" was on my mind for the whole time. Fortunately, that was completed without issue, although a magnet popped off the frame when doing so (guess I'll superglue it back on later). In case anybody expects anything different, there will only be replacement for the regular glass (2pcs), no replacement of the shield-of-mjolnir (or whatever it was called) was included.
I could also see in the cross sectional plane of the glass that it does appear to be more refined than the previous glass panels (has a more sanded appearance than the raw cut appearance of the previous glass).
The BORG also matches the anodization of my kickstarter batch nicely, although to be fair, mine is silver-on-silver so probably the least suseptible to difference. I think some material on the bottom of the BORG instead of just raw aluminium would have made it sturdier as a stand, but I think the EVA foam that comes with it actually may double up as a foot.
This for me concludes the journey with MJOLNIR, I do hope to actually put a custom water loop in it at some point, its just been so long since everything happened that my life circumstances are not so compatible with just lashing out on a new PC without other considerations.... If I do get around to it, I'm sure I'll share it around.
