I just picked up the zenmuse z3 and while it works alright on the x3 board I understand the x5 board is needed for stability. Dest deal I've seen is $89 from this Amazon link, anybody know of a better deal? It's weird that DJI is pushing some crazy deals for phantoms/accessories, but only a few select inspire 1 accessories get only 5% off....weak

also does an inspire 1 + x5 vibration board fit in the stock hard case or will i need another case too?

It will fit in the original case, but you might need to cut a small amount of foam to clear the front area of the Inspire.

This is a pretty nice deal considering you are getting the mounting board and the gimbal camera mount plus the risers.
