Will the serial number be done in the same style as the X, or more like the SnP and Spheroid. I think done like the X would look very classy and go well with the rest of the design.
Just as long as it's underneath or something because if it would be on outside on the base or on the cap (unless the cap can be positioned any way) it would drive me crazy if the SN did not line up with the SN on the X. That would flare up my OCD!
