Some thoughts after installing my RF 88UB in the case, and using it for a couple of days.
I had the same issue with the pcb securing screws as some others have mentioned, where they didn't go far enough in to secure the pcb (or the screws were too short). I couldn't find any metal shavings/residue in the holes, so I don't think that was the issue. But I did see some signs of the threads not going all the way to the bottom of the holes. Perhaps this is the real reason for this issue? Or perhaps the 88UB pcb's are thinner than 87's. I didn't think of measuring the thickness of my pcb while i had it out though.
I fixed this with some nylon washers.
One minor issue with the risers and rubber feet is that the risers interfere with the rubber feet on the short sides of the case.
This is mainly an issue if going from no risers (and all rubber feet installed) to risers installed, since two of the rubber feet would have to me removed.
But I think there is enough material in the risers that it would have been possible to make a small notch/pocket for the rubber feet on top of the risers, so that both could be installed at the same time. But hindsight is 20/20, and it's hard to think of everything when designing something like this.
I will probably always have risers installed anyway, so this is not really an issue for me.
Finally the risers could have been a tad higher in my opinion. Although this might improve if I used a wrist rest, so I'll have to get one to try it out.
But I think it might be possible to make some higher risers in the same design as the current risers, something like this amazing paint illustration shows:
Taller risers for Norbaforce GB anyone??
These are all very small gripes, and I'm overall extremely pleased with the final product. The feel and finish of this thing is fantastic, and the case combined with KBDfans silencing rings has brought my RF to a HHKB-level of tactility and feel.
Here's a final image of my (current) endgame!
Which my wife promptly took off with, claiming she needed it for
productivity or something like that.
