It definitely has MX sliders. I have GMK Laser on mine, fits perfectly.
Nice! How’s the build quality overall? Flex?
It’s great. I’ve only typed on it a little. (Jury duty this week). It seems just as solid as my R2 PFU edition. There is less flex in the case and it feels more solid than either of my 87Us. (Although, of course, way way way less substantial in every way to the Norbaforce on my daily driver )
