Anyone on the fence should just check out Lastpilot's build log of his to see how nice this kit is! 
I would read GLITCH3D's review if you can find it. I was originally set on the Crystal but the "lightness" of its thin frame is what changed my mind to go for the acrylic.
I appreciate the shoutout, and I do love my board. However, I just want people to know that this is by no means a "perfect board," and may not be for everybody. Here is a mini overview comparing the regular versus crystal GON boards:
Normal GON Pros:Nice weight
No bending
The nice refreshing cold feel of aluminum
Very solid "finished" build feeling
Normal GON Cons:Plate can easily be scratched, anodizing seems thin
Typical alu plate feel with slight ping and very_slight_ switch-bottom-out-feel inconsistency (much more consistent than my LZ for example)
Kaliet (22kbd.com) provides cheaper (and more timely) alternatives
Crystal GON Pros:Lighting options
Unique "light and chirpy"
soundMost consistent bottom-out feel of any board I've typed on (PCB mount, alu plate, poker plate, LZ plate)
One-of-a-kind all polycarb board
Crystal GON Cons:Overpriced
Can bend if using the stock feet supplied
Time consuming assembly
SMD LED not easily swapped out or repaired (access to top-facing LED requires desoldering of all switches)
Very lightweight - almost flimsy
As I've said in the Massdrop comments:
You have to be in it for the looks or the lack of ping sound for the crystal to be worth it. You also have to realize that this board is best used _flat_ without the aluminum feet, but instead use some kind of glass table bumpers that you can find at a local store. The board bends under even just a little weight.
