I have a matte black base and stack unit for sale if anyone is interested. Ordered this case thinking it would fit an EVGA GTX 1080Ti FTW3 but it has just a bit of fitment issues, so I'm selling. PM me for more info. The base unit is not in perfect condition, the stack unit is new, only unboxed...
@CubanLegend posted this to be able to control fan speeds to under 37%, if this is what you're looking for.
