Wayne has finished upgrading my Mensa to a Mensa PLUS and will be shipping it out to me. Mine was the very first Mensa and Wayne had learned some new things since then. I didn't have any performance issues with my Mensa but if the Plus takes it a step further.....
I plan to spend 200+ hours breaking it in again as some power supply caps were changed, and will probably be done at the end of the month.
