Drivetrain:
--987 shifter: 15% shorter through than the 9x6 shifter. The 2004 Anniversary edition Boxster has this shifter.
--997 Shifter: 997-424-010-00:
Just installed a new 997 shifter - Page 2 - 6SpeedOnline - Porsche Forum and Luxury Car Resource
Misc parts:
--Airbox: 987 air intake box.
--Top - OEM top and frame from 2004 or 2003 into an earlier car. The advantages of a glass rear window over plastic are obvious. The OEM 4-bow top allows for a larger window and better access than the aftermarket retrofit tops. In my case it also provided a headliner that was not included with my 2000 base Boxster or earlier cars.
--Lights - OEM litronics (I also installed the self-leveling and low beam swivel feature.) While not technically from a later car (they were available starting in the 98 model year) they provide better illumination and are also an appearance upgrade.

--OEM intermittent wipers. I don't think these were available on a base Boxster. I know some people don't drive their Boxsters in the rain, but this is nice to have on a misty day.
--Six-channel amp from a Carrera:

I'm currently working on adding memory seats to the power seats I installed over the last few weeks. Here are some links:

--Rear badging: The later chrome version of the 'Boxster S' rear badge, rather than the matte silver version seems to be quite nice, and also matches the exhaust tips if polished.
