I recently acquired a G84-4100 and I love it to bits. The layout will take some getting used to but if there is no other way I will still enjoy using it as is.
I wanted to know if there would be some sort of demand for a tenkeyless version of the G84? You would basically take all the existing switches/caps and move them onto a new plate and some how new casing might become available. 6KRO might also be a possibility.
Of course I have no experience with electronics. I would have to pester those with this knowledge to help out
