Sadly Loriano didn't collected enough orders to start the production of X500 Plus, so the only way to realize the project is going to kickstart.
In the meanwhile Loriano apported some little invisible modifications to the case in order to make it cheaper. Also he added some bonus features.
Kickstart will begin in few days, though you're not interested in buying one case you could make a little donation helping the realization of this amazing project
I'll let you know about Kickstart as soon as it will begin
