Got mine finished today. Nice build. I'll have to upload pictures sometime later b/c I'm headed out of town. I didn't have any issues with the PCB. I did notice that I shocked myself on the case and it rebooted the keyboard one time. It could have been static shock I suppose. I think the usb port touches the case just slightly. That makes sense, right?
Anyway, very nice board. I really like the bootmapper client software too. I have 67g zealios in mine and I love the typing sound. I ended up keeping penumbra on it, but I'll probably switch back and forth between that and hyperfuse. Since this is my first top mounted board, I was curious to know if I could tell a difference from tray mount. Yep, it's slight, but it does sound a lot nicer.
I did have one non E8-V1 related problem and I just thought I would mention it here. I might make a post about it in the keycaps section as well.
I ordered some ePBT purple on beige keycaps to go on this board. It looked perfect. It would have been the dream. However, I simply could not use those caps with cherry stabilizers. My best guess is that the purple set is a bit more shrunken from the molding process. It definitely fits very tight on the stems. I tried and tried all of the stablizers I had, but couldn't find a set that didn't feel like they were binding. Long story short, it was the ePBT caps. I've experience similar issues with some pbt caps (industrial) from Signiture Plastics that were about 1mm off spec from stem center to stem center. It pulls the stabilizers inward and makes them bind. I will have to use the purple on beige set on a costar mount board, as they work fine there. Boo. I have a red on beige ePBT set that doesn't have this problem.
Oh well... Laser will look amazing on this keyboard some time down the road too.
