CJ, first off, thank you for posting this.
This thread on renntech gives a nice guide to install the H7 HID bulbs into the boxster:

I do have one question. In the above thread, 986Jim mentions the drilling one needs to do into the plastic cover of the factory headlight in order to pass the wiring through (that is one reason I've been holding off on that upgrade).
Is anyone (CJ?) here positive that there is no drilling etc. involved with the bulbs from CJ's link? Thanks very much!!!
