I had some issues with a row of switches not working when I put mine together - F1, 1, q, a were all not working until I retouched some diodes and the controller. Not sure what the problem was but after I added a tiny bit more solder to the controller legs they worked. Anyone else experience this problem? Seemed kind of weird, I've never had an issue with factory solder before.
RE: alu bottom vs acrylic angled - both have their place. I have angled acrylic on my Orion and alu on my Octagon. I do like how the RGB light spills out from underneath the board on the Orion. On the Octagon, the underglow light is only visible at the edges of the board, and without a triangular insert I don't really see the RGB light when typing from above. Even the acrylic side inserts don't do a whole lot unless looking at the board from the side. Right now I just have it matched to my LED color, since the alu and keys are both black and my switch LEDS are orange-red.
